@Cenholi  we have her word. But whole situation is kinda blurry and frustrating because author didn't show a clear scene. We still don't know on 100%.

@Nameless422 i'm afraid she would die in some way, because for teenage girl with emotional instability that's too much.

@Khirud It's working in fiction. In this story you could see that she is really changed. 

But in reality 99.9 modern girls with such experience and behaviour would be huge red flag and this kind of relationship would drive almost everyone mad, because you just cant trust her and her history.

But again, in this manga you really see a transformation and a new start with remorse.

@Niche it's the only way to not destroy a beautiful friendship and not offend other group of fans.

@Krawm i hope it would be just strangely funny and that's all. Because all that bullshit with condom, kiss, moans etc was to obvious. Stupid misunderstanding is miles better than cheating and cuckold drama.
