I just skimmed some parts and I kinda don't like that supposed second couple? Like joo-an vocally pursuing the mc but are they also a thing with Mr. Yeon? It's like he knew that guy likes him so is he taking advantage of it? do they have just a physical relationship? I'm sorry, I'm confused. I know the main couple is cute but the second just kinda bugged me
