Lee Heeseung, the basketball captain and school's pride, he loves you–no, he's obsessed with you. He'll do anything to get your heart even though you already have a boyfriend.

You're tired of him constantly chasing you, so you accept him. You say, "But you're not the only one. Don't complain if I get intimate with Jake in public." And he just nods obediently like a cute puppy.

Five months pass. Everything goes smoothly. He treats you like a princess, he loves you so much. Until one day, he comes to your apartment. Jealous because you've spent the whole day with Jake–your first boyfriend–and haven't had time for him. He says, "I'm your boyfriend too. I want your attention, baby."

You sigh and say, "I told you, you're not the only one."
