Looking for a manga

[Kaizeel]

Looking for this manga where I vaguely remember that the MC was bullied in school, ended up killing himself, and had the opportunity to look back on how his death affected others. Iirc one of the biggest points is that his dad is the principal and was also his anonymous text buddy, who ended up hanging himself in his office during the morning announcement after his death.

And I think he was given the opportunity to change things as like a ghost or smthn. Like if they forgot him he dies for good? Could be wrong. Probably wrong.

In case no one else comments, maybe it's a movie called Colorful. I haven't watched it an quite awhile but it's about suicide.
