I dunno though he obviously has had his heart broken by that guy from the past and I think MD is somehow involved in it maybe the guy was seeing both the guys at the same time... I could be wrong but I do see a chance that he can somehow be involved in it.. he could even be the guy in the photo when he was younger...
It I yaoi world and anything is possible
I think the boy in the flash back is his ex boyfriend and be either left him or cheated on him withMD which is why he's so angry when he thinks the uke went to him and that's why they don't get along I think they all was together in the past as mates ...
