Minho was always in love w Seoin bro! Look at him blushing the first time they talked. Maybe he stayed with Muyeong because that's the only way he could have stayed close to Seoin, who was dating Gi-tae at that time. ヽ(`Д´)ﾉ And maybe he was not angry at MY for cheating but he was angry on Seoin's behalf and beat the shit out of them.
