I can understand that even though I wouldn't mind if it got romantic. When Sakura first came on the scene I thought it would be really refreshing for Yoshinaga to end up with a knowingly gay character.
Well, even if got romantic, i can still except it little bit but it just rare to see manga about relationship between straight guy and gay guy that focus more on their friendship and dont try to made them into lover. This manga currently make me feel like that most BL that involve this type relationship try to tell us: "Straight Men and Gay Men is not mean to become friend unless they proceed to romantic stage" and i dont want it to change. Tohru sensei can introduce other character as both MC love interest and keep the two of them as best friend that help each other on their love live. There is more possibility to this story that they can expand (He/She already did it to some extend by introducing Mayu and Sakura) without involving the two MC got in love with each other.
Even though i am minority in here, i still hope that Tohru sensei keep making the series realistic and that including keeping Yoshinaga and Hasegawa as best friend and not lover. Is nice to read story about gay guy and straight guy friendship that ground in reality like this so i dont really want much change in status. Beside this story remind me of me and my best friend back in high school.
