I became the only Korean character in a Japanese Light Novel.

I used to think that my stealing skill only worked on what was worthless to a person. But just before I died, I realized that I could also steal the skills. So I stole the regression.

A sudden message arrived, heralding the end of humanity. [Climb the tower. If you refuse, you will die.] We are being threatened by a mysterious being.

I saved the Warrior who used to ignore and bully me and now she is obsessed with me.
