Junwon’s sure he’s straight. Yes, all of his girlfriends dumped him for one reason or another, but that doesn’t mean that his relationships will work out if he dates guys. However, a certain someone’s been on his mind. His school sunbae, Jaehyun. Jaehyun’s good-looking, friendly, makes Junwon’s heart pound…and straight. Not only is he straight, but he also used to date Junwon’s sister, Jiyeon. That doesn’t stop Junwon, though. He wants to look at his feelings and find out what he really wants. Everything starts with one question: Aren’t you curious what it would be like to kiss a guy?
