Looking for a yaoi

It's a rather old one, but, it's about three best friends that have been together since childhood and their in highschool now. Friend A and B see Friend C confessing to someone else and Friend B uses the chance to confess to Friend A, so Friend A and B start to get closer but, turns out Friend C likes Friend B and gets jealous of the other two, (mostly Friend A), and tries to ruin their relationship.

They also have this tree where they carved their initials in and I think Friend A ruins the carving or something cause hes upset that their friendship is falling apart┗( T﹏T )┛
