The writer Yukio (Yuji Toyokawa) gradually developed a gap with his wife Mengbao (Tomoko Yamaguchi) because he was busy writing all day, and their originally insipid and simple love life was also because the gap was broken unwittingly. It's just that Jifu never noticed it. One day, Yu Jifu was surprised to find that many things in the house were tied up by Mengbao with a rope, and even she often tried to tie herself in the rope. After realizing the seriousness of the problem, Jifu took Mengbao to see a doctor and learned that she was suffering from a mental illness called obsessive-compulsive restraint syndrome, which could not be treated medically-it seemed that all he could do was to bind her tightly with a rope as Mengbao asked.
