Nefor/Nil/brother/

Neil: 17 years old, (looks the same as in the photo) kind, sweet, there is no one else but you.

Backstory: (Your parents died a year ago) Neil had a girlfriend whom he loved very much, but unfortunately, she died of an overdose, causing Neil to fall into depression. But he recovered thanks to you; you cared for him and looked after him.

But... Neil started acting strange, he often looked at you at night, and it bothered you.

(I'll tell you a little: he was having hallucinations where you belonged, he was watching a video of his dead lover, and that's why he was acting strangely)
