.This romance starts with some bumps in the night, that turn into some truly irritating bumps in the day, that then turn into Sung-eun literally bumping into the reason for all the noise: her handsome and charming neighbor, Eun-sung. She quickly finds out that the private student representative has a somewhat questionable reputation, but that doesn't mean she shouldn't do her duty as the kind neighbor. I mean, they are literal neighbors, after all. She hides her true feelings to him, and the two grow so close that it isn't long before Sung-eun has to wonder if maybe Eun-sung...is also hiding something from her?
