He doesn't need a girlfriend, but he wants some sweet sex. He wants to go on romantic dates but doesn't want to be tied down. Convenient relationships like this are hard to find. Ryo is a student at a vocational school, usually studying fashion design, but he's the only one who can appreciate her beautiful legs. But he can't start a new relationship because he's afraid of getting hurt if he's betrayed. No, come on, he's the one who's cheating on her, haha.
