俺以外にはときめかないで

Thanks to his tenacity, college student Rio has just landed himself his first boyfriend: the suave and mature club bartender, Chiaki. But while Rio obsesses over his mega hot "Mr. Perfect," he also begins to worry he might not be good enough for him. Then, when Chiaki gets the idea that Rio wants to break up, he suddenly grows desperate. Turns out Rio's new boyfriend is actually quite (endearingly) clingy!
