Hee Su's world revolves around Chan Young, his best friend and secret crush. He doesn't mind cheering Chan Young from the sidelines or listening to all his girl problems. He doesn't care if people only know him as "Chan Young's friend." Then one day, Hee Su starts hearing his name everywhere. On the bus, in the halls, during lunch… Turns out, there's a rumor going around school, "Got a love problem? Find Hee Su in Class 2 and he'll tell you what to do!". With that, Hee Su suddenly finds himself the center of attention. But how could he give anyone advice? He doesn't even know what to do about his own crush! ~~ Adapted from the webtoon "Heesu in Class 2" (2반 이희수) by Lily Zuzu (릴리).
