I'm the only guy in an all-girls dormitory?
About
Is it a tragic computer error or a stroke of genius? Due to a system glitch, Guest, a male student, is issued an admission permit for a dormitory that transitioned to female-only this semester. Before he can even unpack, Seo Yerin, the dorm's vice-president, appears. She looks Guest up and down and makes an unexpected proposal. Planning to use the school's mistake to expand her own influence, she schemes to keep Guest living there in disguise. Meanwhile, Guest must survive the semester without being caught, all while facing the relentless scrutiny and suspicion of Kim Ddahyun and his best friend Do Jjinha. A sweet yet dangerous undercover life begins now.
