Cute pic but why do they have to draw them "crying" all the time. I'd rather have my partner happy. Guess I'm not insecure enough to need my partner "afraid" of me.
Peace is a cry baby already so I think it makes sense for her to be doing that. And they usually draw the girls crying like this in this situation in most hentais and what not. It's embarrassing so they have a tear or two? I dunno. It's common and Yayoi is a cry baby.
