Synopsis: Your Junior Will Help You

"I really can't live with this bastard." Sunbae Gong Chae-eon and his junior, Nam Geon-oh, are roommates who clash on absolutely everything. Chae-eon hates every little thing Geon-oh does. Meanwhile, Geon-oh is sick and tired of Chae-eon's nagging and is just waiting for a chance to find a weakness to exploit. Then one day, something that shouldn't be leaking starts flowing from Chae-eon's chest. He desperately prayed that Geon-oh, who lives under the same roof, wouldn't find out, but he ultimately gets caught in the act. However... completely unexpected words come out of Geon-oh's mouth. "I knew you had weird tastes, but this is beyond anything I imagined." ...Should I help you?
