I read it a few years back, but I can't remember the name. It was a shounen-ai/yaoi, and the art style looked a bit older - like the late 90s era. As for the story, I think it was about a guy whose friend had moved away, but when he came back, he was acting cold, and he was with a girl (who at the end got married). The uke (the guy whose friend moved away) was straight (originally) and had shorter black hair, if I remember correctly. The seme (the guy who moved away) was gay and had liked this friend for quite a while. He had longer, lighter hair, I believe. Anyone recall reading something like that?

Never mind. I found it. The title was Kimi no Mukougawa. It was from year 2000. So close. Kinda funny how the art styles have changed over time, though, huh?
