they can't go out with each other because Okozono basically doesn't want to start a relationship with Yamashiro because if he does, it might end someday. That's his philosophy~ So his twisted way of loving Yamashiro involves stealing things from him including the people he goes out with.. And somehow Yamashiro also plays the game.. He's aware what Okozono does and in turn uses people for Okozono to steal..
but in the raws you can see the last part okozono finally end what he feels a yamashiiro(i am from argentina, my english is really bad sorry)and what about murata , he stay with yamashiro im the end?????(⊙…⊙ )
oh you mean ch.1 of the raws? I think that's a different manga.. Yamashiro and Okuzono's story is a one shot, so it ended in that one chapter.. Murata- is he the guy who confessed to Yamashiro and had sex with him in the library? In the end he told Yamashiro that he's sorry, wanting to end their relationship and it seems it was Okuzono who stole him as
again'''''???????? dont tell me.
i believe that okuzono dont wanna stay with him(murata)and let it go to yamashiro????
