Pay Off Your Debt

Shikagawa is reincarnated into another world and is told by the system, Yoshika, that he cannot return to his original world unless he completes 100 missions.

He did as he was told and drove the villain Fu Hanjiang into darkness 100 times, but his grudge nearly destroyed the system, so he was given the opposite order, to rehabilitate him this time.

Feeling heartbroken, Shikagawa reluctantly heads into the world of a typical Cinderella story to rehabilitate him.

"I'll break both your legs so you'll never be able to escape from my side again," "I prefer a captive canary to a bird that sings freely," and many other yandere lines are uttered by Fu Hanjiang, but for some reason, Shikagawa is gradually drawn to him... Will this villain rehabilitation project be successful?
