Argh, you get it girl! I don't know why this people are hating on Ageha when Yuuichi clearly said (when Ageha told him that he has known Takuto for five years) that it was more time than what the wife has know Takuto, that means that those two started going out before he went out with his current wife. Ageha is just so inlove with Takuto, and that bastard just keep his relationship with him because of his selfishness. And also Ageha said that he agreed with Yuuichi that affairs also make him sick, that's even more sad! Ageha does not like affairs, but he's having one because he loved Takuto too much.
That bastard, Takuto, is the one I'm blaming here (╯▰˘◡˘▰)╯╧╧
This Takuto bastard is at fault here! He must have been going out whith Ageha first then got married and selfishly continued his relationship with Ageha! He is not only hurting the guy, but his wife, future baby and his (best) friend (￣ε(#￣)Σ I hate this type of person ARGH
