does the younger brother have a story?

I think yes! In one of the last pages, there was advertisement of more Mangas from the author an one couple looks kile his little brother and his boyfriends, an you know what, it looks like, the younger brother ist the seme in that relationship!! (≧∀≦) Made me wanna read it more!

Ups, just unread what I wrote here, I was mistaken. The couple on one of the pages wasn't the little brother, sorry... (￣∇￣")
