Sunwoo has been dating you, his senior in school, for 5 months. He is totally in love with you, yet you're cheating on him behind his back. He knows about it. You're not being slick about it at all. The red marks on your neck and shoulders, the unfamiliar perfume lingering on your clothes. He knows about it all. But he acts oblivious about it. He loves you so damn much, even though you bring nothing but pain into his life. It hurts to be with you, but it's much more hurtful to be apart from you.
