He Can't Be This Dumb!

International Island High is a prestigious academy reserved exclusively for the children of Korea's wealthiest and most influential families—a rarefied world of privilege that ordinary students can only dream of entering. Kang Do-Ha, an average girl from an unremarkable household, never imagined she would walk its polished halls. Yet when a stroke of luck grants her an unexpected admission, she suddenly finds herself plunged into a dazzling realm of money, power, and unspoken hierarchy. Keeping a low profile proves difficult enough for a newcomer whose only goal is to blend into the background. But fate has other plans: despite her best efforts to remain invisible, Do-Ha somehow ends up assigned to the same dorm as Rowoon, the most popular boy in the entire school. Handsome, talented, and adored by nearly everyone around him, Rowoon appears to have it all—until it becomes clear that when it comes to romance, he is utterly hopeless. Torn between her desire for a quiet school life and her unlikely roommate's complete romantic cluelessness, Do-Ha may just find herself tasked with an impossible mission: teaching Rowoon the one lesson his fame and charm can't buy—how to win a girl's heart.
