First story was really good, I have mixed feelings about it, I felt really sad for Seono and for Hirono I was both sad and very pissed, how could he do that to Seono, his own brother?? (I know it's difficult to overcome it but I guess he was a little insensitive).
Anyway I enjoyed both stories, first one almost made me cry.
Awww I really wish MD and Changwoo's story were longer! Specially bc of all the bdsm aspect ლ(´ڡ`ლ)
