Neoui Sarange Daehayeo

Yo-Han is no stranger to unrequited love. As a child, he watched his older brother suffer that pain, and he knows the person with feelings always loses. So when he spots his senior, Mu-Gyeong, mooning after another boy, Yo-Han decides to step in. Confess or give up is his motto, that is, until Yo-Han’s the one with the crush on Mu-Gyeong.
