Seojin only meant to return a package. A package that definitely wasn't his. A package addressed to the quiet neighbor across the hall. And a package that, judging by the giant LOVENSE logo printed on the side, was far more embarrassing than either of them would like. Unfortunately, Minju opens his door at the worst possible moment. What follows should be a brief, awkward interaction between two strangers. Instead, it's the beginning of a friendship neither of them expected—between a cynical young man carrying too many secrets and a university student who can't seem to look away. After all, everyone has something they're hiding. Some secrets are just harder to keep than others.
