This was the first shounen-ai manga I've read in my life, and definitely the best one too (Bloom into you and Whispering me a Love Song are also great shounen-ai and shoujo-ai mangas)!! The character development of Leo, from being a seemingly deliquent-antisocial loner guy (he was still kind inside during his high school days too) to a normal guy enjoying his University days and experiencing a genuine affection towards Junpei, it's really one of the best character developments I've seen in mangas and animes..
I am really excited for the next serialised volume!! ๐โจ
