The protagonist, Choi Si-woo, found himself in a very difficult situation.
Of all things, he was being dragged by a blunt weapon. If only Yoo Eun-ha had just quietly stayed at home, this wouldn’t have happened.
Lee Yoo-jung was an absolutely essential woman for saving the world.
He had a plan to meet her later, unlike before his regression.
However, now that Yoo Eun-ha had already met her, he decided to blow up the situation in the cafeteria and try to get closer to Lee Yoo-jung instead.
In his past life, he had many experiences with her, but now it was different. He had been labeled a "talkative girl-like guy," so he thought it best to establish any connection he could.
Harem relationships were only formed because he had been pulled into them; he didn’t actually desire one. The world was more important.

“Yoo Eun-ha, you damn bitch. Just you wait. I will get my revenge.”

Yoo Eun-ha?
As he rushed toward the cafeteria, he turned his head at the words spat by a girl with copper-colored skin he passed by.

“Hey, did you have a problem with Yoo Eun-ha?”
“Ah, well, that Eun-ha girl insulted us and beat us up, yet the student council only gave us points and 20 hours of community service…”

Yoo Eun-ha wouldn’t do that.
These dimwits were trying to pin everything on her.

“The student council doesn’t give points or assign community service to innocent people. You must have done something wrong, right?”
“Ugh.”
“If you touch my friend one more time, I won’t just stand by.”

As he emitted a killing intent, the thugs turned tail and ran.
In the past, before his regression, he might not have acted this way, but now he couldn’t afford to be distracted by such matters.
He needed to protect the world, and if those punks became villains and touched Yoo Eun-ha, it would be dangerous.
Having released his aura, they wouldn’t try anything foolish.
As he arrived at the cafeteria, what caught Choi Si-woo's eyes was the sight of two girls, half undressed, embracing each other.

[Oh wow.]
“Girls can do that too?”
[Stop pretending to be innocent.]
“No, I’m a guy, so I don’t really get that.”
[Since the factions are predominantly female, there’s a lot of yuri. But that’s a real masterpiece. By the way, are you okay? You were dating her before your regression, right?]
“Something has changed in the priorities.”
[That Yoo Eun-ha? Her technique is incredible! Wow, Lee Yoo-jung’s waist is bending like a bow. What the hell is that?]

However, it felt strange to be watching.
After all, Lee Yoo-jung was his girlfriend before his regression.
Since he had made up his mind to stop the apocalypse this time, he didn’t desire a girlfriend. But seeing this made him feel like he had lost one to Yoo Eun-ha.
It was particularly strange that she was making her feel so good.

“Wait, but if it’s between girls, what about purity?”
[Do they even care? Wow, she’s really good. I wish I could possess her.]

Amidst all this, the two were indulging in each other, sinking into the depths of pleasure.
Lee Yoo-jung's bright red, pulsing body was being thoroughly caressed by Yoo Eun-ha’s fingers.

Gulp

Even though they weren’t dating now, the feeling of having lost Lee Yoo-jung made his stomach churn, and he wondered what it would be like if he were a woman.
What would female pleasure feel like? He felt genuinely curious.
He had never seen Yoo-jung tremble with such delight before.
Above all, he unconsciously thought about wanting to experience such things with Yoo Eun-ha.
After all, since Lee Yoo-jung had fallen for her, it wouldn’t be a problem for her to continue fighting against the apocalypse.

“Wow, that’s…”
Before he knew it, memories flooded back.
Back when Han Soo-ji had asked him to treat her like that and showed him some adult films.
But that was nothing compared to this.
It was clear that this was an intimate act between women, yet it looked incredibly lustful.

[Seems like she only likes girls.]
“Um, do you know how to become a girl?”
[...I’ll find out. But you have to lend me your body once.]

The sword user, Choi Si-woo, and his divine sword. Unbeknownst to them, they were both falling under Yoo Eun-ha’s bewitching charm.

Once the regular classes at the academy ended, our protagonist called all the heroines together.
Since it was the Internet Broadcasting Club, they chose a dungeon.
The academy likely opposed this due to the threat of the Black God Church, but it seemed that our esteemed sword-wielder had persuaded them somehow.

“Wait, this party composition is really weird, isn’t it?”

Choi Si-woo was a sword user.
Reina was an archer.
Han Soo-ji was a spear-wielding warrior.
Lee Yoo-jung was a hacker specializing in electronic warfare?
And then there was me, an irregular just swinging a steam-powered knife.
In short, we were all dealers. No, Lee Yoo-jung would be limited in her electronic warfare since it couldn’t be used in dungeons.

“But isn’t it strange to have no magician or healer?”
“Don’t worry. I brought an emergency treatment kit. I bought it with the club’s budget, and it’s full of potions.”
“But you’re not a healer.”

Wait, isn’t a potion just support for a healer?

“I figured this would happen, so I chose a dungeon where mechanical monsters appear, allowing Lee Yoo-jung to participate.”
“And Yoo Eun-ha?”
“There's a saying: The best defense is a good offense. If you hit during the time you’re defending, that’s enough.”

In other words, it meant “Dealers unite.”
This guy wasn’t like this before, was he?
To put it bluntly, it felt like he was trying to organize a balanced party with a tank, dealers, supporters, and healers.
But now it was all dealer-focused.
Lee Yoo-jung’s electronic warfare might not work against biological monsters, but it was excellent against mechanical ones.

“I’ll just follow behind. I want to see your skills today.”
“Oh, is that so?”

But then that guy occasionally glanced at me, his face turning red.
What’s he up to?
Is he seriously thinking of trying to win me over now?

“The dungeon’s name is Mecha Land. The recommended hunter level is C; is that okay? We haven’t done proper dungeon practice yet?”
“We can just do it now. Yoo Eun-ha will lead, and I’ll stay in the back.”

This bastard is trying to push the responsibility onto me.
Well, observing Lee Yoo-jung’s abilities firsthand wouldn’t be bad either.
First, let’s explain the mechanical dungeon.
It has an SF vibe to it. The monsters are robots with cores, and there are lots of traps. There are even lasers that shoot, and if you touch them, missiles come flying, or limbs get cut off.

“Oh, so that’s why they say dealers need to unite.”

Choi Si-woo, the sword user. His sword, the divine sword. Both were unknowingly falling under the spell of Yoo Eun-ha’s charm.

After entering the dungeon, they soon heard,

“Gah!”
“Gah!”

What the hell is that bastard doing in the back?
He seemed to be following properly, but the occasional screams made him curious.
Was he trying to set up a haunted house concept in the back with some kind of recording?
Let’s just give up thinking about it. I don’t want to think about it anymore.

“Oh, a trap room.”
“Step aside. I don’t want to get caught up in anything annoying just because I’m trying to get some treasure.”

He had been in a mechanical dungeon once in the past.
Mecha Land. The name of this dungeon was the same, but it was only described in the text, so he didn’t know if it was the same place.
However, judging from the description of the trap room, it seemed that triggering the treasure chest would unleash missiles from all sides.
Honestly, if he used electronic warfare, it would be a piece of cake.

Bzzzt!

Suddenly, electricity flowed through the walls of the trap room, and the lights went out.
This indicated that the trap had been triggered.
Looking to the side, he saw Lee Yoo-jung smiling with her eyes glowing blue.

“Wow, this cheat is amazing.”

In the original story, during this time, Choi Si-woo would try to protect Lee Yoo-jung while she attempted to use electronic warfare but couldn’t.
Anyway, this Choi Si-woo was such a burden.
He was fine behind her now, but the screams from time to time were still concerning.
But witnessing Lee Yoo-jung’s electronic warfare firsthand was genuinely amazing.
Just activating it with her eyes was destructive.
How comprehensive must her electronic warfare ability be?

“Is there anything we need to do?”
“Well, this senior is practically a cheat.”

Reina and Han Soo-ji complained as they opened the treasure chest.
The things that came out were all gold bars.
If this kept up, they could probably live off this for a while.
After deducting taxes for the association, splitting it among the five of them should yield a decent amount, even if it was just the value of the core.

“But what’s Si-woo doing in the back? He keeps making strange noises.”
“I don’t know. He’s sometimes weird.”

Now he was being treated as a complete weirdo.

“At first, I felt a little attracted to him rationally, but how should I put this? There’s a creepy vibe behind that smile. No, I don’t think that’s bad, but he doesn’t give off the feeling of wanting to date.”
“Right? He’s handsome, but it feels like there’s some pressure.”

Choi Si-woo had already lost three heroines.
Wouldn’t he end up becoming impotent at this rate?
But something about him felt strange. Did he know Lee Yoo-jung had the capability to wreck this dungeon?
Why would he need to come to this dungeon at all?
What was the reward here?

“Ah.”

The reward for clearing Mecha Land was <Legacy of the Ancients>.
As the name implies, it contained knowledge preserved by the ancients, which could be bound to him if he used the Yatpect.
In the original story, it was handed over to Lee Yoo-jung’s older sister, Lee Yoo-jin, who was a contemporary representative of the Cheonsan Group, allowing Choi Si-woo to receive support from the group.
However, midway through, <Legacy of the Ancients> was temporarily brainwashed by the villainous organization known as the Black Dragon Society, and it ended up going to them.
That allowed the Black Dragon Society to greatly develop, gaining strength to the point of clashing with a large company like the Cheonsan Group.
There was no way he could regress, right?
If he was targeting the <Legacy of the Ancients>, he should have realized there were other ways to acquire knowledge, not just this dungeon.
How did he even know about the rewards here?

[Intruder detected. Golem defense system activated.]

Suddenly, various metals appeared in mid-air and began to combine into a single form.
They were the large golems he was encountering for the first time.
The golems looked quite solid, and they were indeed sturdy.
Generally speaking, they were immune to physical attacks, meaning he would need overwhelming strength compared to them to do any damage.
Yeah, what more was there to say?
As an irregular using <Acceleration> and <Parallel Circuit>, he would find it hard to inflict damage on that damn thing.
Actually, something felt off about this body.
His strength wasn’t increasing as easily as he had hoped.
It wasn’t that it wasn’t increasing at all, but those with awakening powers were inherently stronger than regular people.
Naturally, their physical capabilities would also differ.
Then, shouldn’t he be using elemental magic like Reina’s spirit arrows or Han Soo-ji’s elemental weapons?
Magic was too much of a hassle, and obtaining weapons was difficult.
Now, Reina and Han Soo-ji were actively engaging the golems.
Since they had already removed all the traps, it was their time to shine.

“Ehh.”

He felt like a troll, watching from the sidelines.
In his current state, Lee Yoo-jung had wrapped herself around him.

“No one is perfect.”
“What do I have that’s worth it?”
“It was the first time I saw someone faint like that.”

He should just drop the topic. At that moment, he had flipped the switch and gone beyond himself.
Ah, well, he had at least protected her in the end. There was no ignoring the law of bolts and nuts.
There were limits to everything.
He never expected that Lee Yoo-jung would let out such moans.
Back in the day, he had poured all his techniques into her, and now he had done the same again.

“But I might be able to deal with that.”

Occasionally, spheres would pop out from the walls as golems.
They were spheres with four legs, resembling units from some strategy simulation game.
Their attack method involved either pouncing on him or shooting bullets from a hole in the middle, which was annoyingly troublesome.
But they were small, and the golems’ cores were clearly visible, so he dashed forward, pressed down on the joints of the spheres’ legs, and stabbed them with his knife to kill them.

Crack!

With just <Acceleration>, he could easily subdue the small ones.
Mecha Land was a maze-like dungeon.
As Lee Yoo-jung smashed through all the trap rooms with electronic warfare, they easily made their way through.

“I didn’t expect the dungeon to be this boring. It’s all your fault, senior.”

Reina and Han Soo-ji voiced their complaints.
Well, that was true. Lee Yoo-jung was doing all the heavy lifting by herself.
Originally, this part of the dungeon story was meant for the protagonist, Choi Si-woo, to shine, but with him hanging back and making strange noises, everything was going smoothly thanks to Lee Yoo-jung.
He suddenly felt a thought arise: Wouldn’t these girls do just fine without him to protect the world?
