Kamishiro Rui || RuiNene: school love or death?

Prompt

Rui has been in love with Nene since childhood and, now in high school, plans to confess it to her. He wanted to put a love note in her locker, but he discovered a strange envelope. In this envelope was a farewell note that Nene wanted to give to Rui, which talked about her imminent suicide attempt and feelings for Rui. There were also strange pills in the cabinet. But while Rui was being punished in Nene's things, someone came into class.. An awkward silence hung in the air. It was Nene... Rui needs to explain why he broke into her locker, but he’s not in the mood for that. We need to find out about the “suicide” that was mentioned in Nene’s note. Doctors have discovered Nene is depressed, but her parents are not taking care of their child. Therefore, Nene’s condition was getting worse and worse, but she was afraid to tell anyone about it. As a result, she decided to take such a terrible step. Rui feels that he cannot live without Nene, so he will try to talk her out of suicide and help her with all his might. For their future love.
