I totally agree about Chika and Masato. About Hosaka I think that the episode with the teacher changed him. While he kept being a very nice guy that took initiative and helps others he became distant and a bit frightened. Also he loved Masato deep down and even without realizing it he stayed alone because he would never act on it. Chika approached him while he was tired (from work and loneliness) and it was a no-loss scenario for him. That's why he didn't go with the flow and said that he loved him. Chika had feelings but was also a bit of a selfish bastard. That is my opinion in general. A good author does not expose everything but leaves your mind to fill the blanks. Of course sometimes due to that (especially from very young readers) I see opinions like " I didn't understand how come he start loving him, or why did this happened" when some things are left to our imagination and logic. Same with some movies. Too much exposition (on Comics or movies) is not always a good thing
Really. Chika forced his feelings and knew he was forcing them. He only accepted the fiance to force himself to give up on Hosaka.
Masato is probably the only one of the three i like, he took responsibility and only acted on his feelings once his wife wanted to split for her own reasons.
Hosaka bent everywhich way and was incapable of drawing the line between whats you do as a friend and a lover. His refusal to say he loved Chika was the one and only time he had a backbone. He doesnt straightup admit to loving Masa but it was alluded to by the descriptions of his smell and differences in the kisses.
Sure its not a loveylovey super feelgood story but it has actual plot and complex characters that dont feel thrown together at the last minute
