Little uke was in love since he was in 6th grade, seme was his neighbour, and was 5 years older! Uke kinda confesed when was in 8th grade, he asked yo have a only night, but seme didn't let him even say "I love you". The Uke grow up with the complex of not being "cute" cause that obviously the seme's type.
Was physically painfull seeing the poor uke strugling to get the seme atentions and never getting anything at all, always being jelous and sad.
Okay, the seme had the whole "living togheter plan" and all, but he was kinda mean to the uke, I understand that he didn't want to be a pedo or a molester, but was really selfish at not saying nothing to the uke (not having him but not letting him go either) poor uke lived in pain FOR YEARS! I would had rather having him to chose his children friend, at least he was kind to him.
