Zutto Kimi no Turn

Kou, a party-goer college student, leads a flashy campus life. Yet he's actually an unassuming guy and, secretly, a closeted gay otaku. His goal is to "get a fashionable boyfriend!!!" Unfortunately, he's never met anyone, nor has the courage to come out. Then one day, Tanaka, whom Kou meets at his favorite game store, suddenly confesses to him. Tanaka is a fellow otaku and the two have a great affinity, but what if Kou simply isn't willing to accept his dull and tacky appearance...? The happiest, most bittersweet coming-of-age love comedy, dedicated to all otakus who hate themselves and want to change!
