She was trapped in depression and twisted love and couldn't move, but he would slowly come to her side, protect her, and give her all his tenderness. She thought he was pitying her, or that he was very good, but she didn't know that he wanted to be good to her just because she was her, and because he wanted to use her to make up for the isolation and helplessness he once had. People who have experienced the abyss know the texture of the abyss, know how to climb up from the abyss, and know what the falling person needs when standing on the edge of the abyss and looking down. Two-way redemption
