When Wushin moves into his new place, the last person he expects to run into is Jaehyeok, the same guy who made his school days a living hell. Out of work and behind on rent, Jaehyeok ends up crashing at Wushin’s apartment, turning his peaceful new start into pure chaos. Instead of the terrifying bully from his memories, Wushin now finds a lazy freeloader who trashes the house and drives him up the wall. But the Jaehyeok he remembers wasn’t always like this; he used to shine so brightly it hurt to look. What could have happened to turn him into such a mess, and can Wushin survive living under the same roof as the one man he swore he’d never see again?
