I Was Locked up by the Heroine While I Was Still There.

After being transformed into cannon fodder, I stayed in the cave every day to watch dramas. The system told me that I would go home until the finale. Until the most powerful female devil in the book opened the door of my house and said that she saw me as a partner for dual cultivation. The system crashed on the spot, and before dying, I was given a new task: capture her. But the problem is - her favorability level is already full. I wanted to run away, but she said she was tired of it for once in her life.
