My Unstoppable Gaydar!

Munju, an upperclassman in Seongha's department, is rumoured across campus to be gay. He is not. He has an early chance to say so and loses it, because the moment he might have corrected the rumour is the moment he accidentally sees Seongha's chest, and the correction never gets made. Seongha is a first-year student who has never dated. Every man she has liked has turned out to be gay, which she puts down to her own gaydar. Then she starts noticing Munju, and hears what people say about him. The rumour keeps spreading. Other students get involved and add their own interference. The two of them keep circling each other while the misunderstanding stays in place.
