Help me find this

A manga/ Webtoon? That was adapted into a short series. Two male leads—not BL. They’re friends in university I think and they share an apartment? One of them wears glasses and the has hair around his ears I think. There’s this scene I recall where one of the is using the bathroom and the other accidentally sees him showering? It’s a running gag because there’s a window in the bathroom leading to the hallway. It was really funny. Help me please yall
