Murder Incident Solution arc
Ai ended up being caught by Gohin, who took her in as a new patient for rehabilitation. At first Ai begged him to sleep with her, but Gohin rejected. She tried escaping on several occasions, but Gohin prevented her from doing so by staying firm and diligent in the treatment.

After four months of treatment, Ai and Gohin celebrated her rehabilitation with a dinner, where Gohin expressed his satisfaction for Ai's progress. After dinner, Gohin told her that he wanted her to return to college, get a job, and live with pleasure. Ai revealed to him in between tears that she would be surrendering to justice the next day. Gohin remarked sadly that it was shame he had never seen her smile. Ai promises him that once she leaves prison she will smile for him.
