To take revenge on her two-timing scumbag ex who cheated on her and shattered her lifelong dream, a prodigy female soccer player disguises herself as a tomboy, assumes her older brother's identity and gets admitted to a top-tier elite all-boys academy. She accidentally ends up as the "male roommate" assigned to the bed directly opposite that of the arrogant, irascible chaebol school team captain. In this ultra-stressful awkward high-stakes scenario where her real gender could be exposed at any split second, a forbidden sweet fluffy romance and satisfying underdog rise-and-payback story unfolds, which makes the originally straight captain fall madly and hopelessly for her!
