This isn't the story of a female mage claiming to be a reincarnator from a romance fantasy world with a secret birthright. Nor is it a fierce adventure of the youngest son of a northern duke who has returned from the past. It’s also not about a deranged second prince, suffering from mental illness, suddenly shouting about status windows after a dimension shift.

It’s simply the story of a knight who, after a head injury, regains memories of his past life as a non-commissioned officer.
Just like any ordinary office worker who always carries a resignation letter in their heart, it’s the tale of a public servant striving for retirement.
