You don’t have to worry about that . This manga is really well made even its end.A big part of senpai's character is that they don't associate themselves with one gender more, so ending the series with them only being one gender for the rest of their life doesn't feel right
Not to mention the bondage...This series has impressed me so far with how informed and nuanced it is when discussing gender identity,
Hé, hé."So that way, Ryou-kun, you'll be the only one to touch me, okay?"
Wait, I thought they did it in the night (or evening), judging by how dark the windows was.Damn, she really asked that in broad daylight, in-front of everyone.
