Looks like there's a lot of missing text, but it seems Hisao had another heart attack, and Hanako saved him with CPR. Hisao wakes up in the hospital with broken ribs, and they plan to put a pacemaker in. Hanako is in a locked facility for mental patients. The doctors tell Hisao about how Hanako ran from a boy who confessed to her in middle school, and when the boy chased her he got hit by a car and died. I'm not sure what happened when Hisao had the heart attack, but apparently he was also chasing Hanako.
You can choose to disobey the doctors' orders to not see Hanako. Hisao and Lilly go to her room and find her mumbling "I killed them all." She sees Hisao and freaks out and shoves him in the chest and he starts puking blood and dies.
If you wait, Hanako visits you after the pacemaker is put in and the doctors allow her to leave. Everyone goes home but Hanako is unresponsive and just stares with her head down. Over the next few days, Hanako continues to act all zombie-like, barely conversing even with Lilly. Eventually she is in Hisao's room, and asks him why he loves her. Hisao can't really answer immediately, and Hanako claims that he wants her body and begins to undress, and lays down emotionless on Hisao's bed. You can choose to have sex with her or tell her to get dress.
If you choose sex, as soon as you penetrate her she freaks out about how Hisao really does only want her body. Hisao stands up quickly in shock, trips because of the pants around his ankles, and breaks his neck on the desk. He is paralyzed, and dies right after Hanako calls him disgusting.
If you tell her to get dressed, she does and leaves your room in tears. Hisao realizes that Hanako isn't the same person anymore and goes into her room and tears it apart looking for her pills. He flushes them down the toilet. The next morning, Hanako acts normal, claiming that it feels like the fog has been lifted from her mind. Hisao excitedly invites her on a date. They go to a park or something where they had their first kiss. Towards the end of the date, Hanako acts more depressed than usual. She says she's sick so she wants to take the subway home instead of walking. At the subway, she talks about how all she ever does is hurt and kill people, and that she doesn't want to hurt people anymore. She throws herself in front of the train.
