So I recently read this manga and I already forgot the title. Anyway the story is about these two friends who happen to live next to each other. One of the guys(#1) started falling in love with his friend so he started to avoid the friend(guy #2). One day guy #2 was standing in a tree and guy #1 one saw him but avoided him. Since then they drifted apart until guy #1 finds out that guy #2 wrote a letter to him but it got lost in the mail for a few years.

This is all I remember but I hope someone knows what i'm talking about. Anyway thanks in advance.
