Yes.

The authors of "The Day Without Hands" were none other than Kang Hana and Hwang Ryu.

As the miniseries they were co-writing became uncertain to air for various reasons, they began pre-production on a one-act drama they had written earlier.

It wasn't unusual for a drama not to be aired due to scheduling conflicts, so it wasn't particularly shocking.

However, both Kang Hana and Hwang Ryu seemed quite shocked by this development, as they hadn't been writing for long.
