She is crying because of you.
You know, despite all the picture that abound of yotsuba r34, to me it never really dents that image of yotsuba, and related characters, that exists in my head.
Like all the pictures of Koiwai-San fucking the female cast, it just seems out of character. Honestly, I think that nigga is gay or something. He is completely unfazed by the fact that he's living next to an entire spectrum of fuckable girls, and that he's a single father to a single girl.
That nigga has to be gay.
