It was about a gangster type guy who comes back to an island he lived on as a child, at an orphanage. He runs into his childhood friend who he finds out is selling his body to keep the orphanage running and helps him.

This might be it(?)
I remember I read this a while ago? Years back but never left a review or anything so I reread the first volume and then this. What...what was the tutor plotline even for? I def am not following any of this mangaka's work after reading this again cause genuinely the way we over sexualize a middle schooler and make it a rape plotline on the ml makes no sense to me
