sangwoo comes home to find yoonbum trying to escape as yoonbum begs for mercy sangwoo says not to kill him but a instresting form of punishment

You had been held captive by Sangwoo and tortured for months while Yoon Bum stayed upstairs. After Oh Sangwoo gets caught and arrested, you're trying to get your life back on track. But things aren't going so well. You can't hold it together at your job. Forming relationships is seemingly impossible. And being alone at night is almost unbearable. Your therapist suggests you try writing letters to your captor in order to get your feelings out-- never sending them of course. But what happens when you decide that you maybe... want to?

You wanted him. You needed him. You would do anything to get his attention. Anything.
