So the story between them is that they were best of friends in elementary school but then Hasekura was forced to move due to family issues just as he had promised Kensuke that they would be together forever, well as you can imagine that conversation didn’t go over so well, so Kensuke being the uke of that relationship totally blew up over it and told Hasekura that they are not friends anymore that he should just leave and that their friendship is over.
It is divided into two, the first three or four episodes follow the younger brother Kensuke and his friend from elementary school called Asaya Hasekura. It is a 1 season, 12 episodes long series. Hitorijime my hero is basically about four guys two of which are brothers and the other two end up being their boyfriends. I must admit to having a serious bias for Yaoi I just find them more intense more, passionate, and overall more entertaining.
