i'm a little confused about why seol-a says "I'm terrible, aren't I...? You're probably shocked at how utterly terrible I am, right?"
is it because she seemed kind of demanding when she said she wanted to sleep over at no-rae's? like something along the lines of needing to have things her way or something? 'cause it didn't really seem too much like that to me and that doesn't warrant her claiming she's "utterly terrible" that no-rae must be shocked. am i missing something or just being stupid and not reading carefully enough?
Hmm the Korean phrase (못됐다) refers to having a bad personality, being mean/rude, being an asshole, etc. I think in this case, Seol-a was saying that she's a bad person for acting like a stubborn child. No-rae told her that she should go to bed because sleeping on her shoulder wouldn't be comfortable, but Seol-a insisted that she was comfortable, and she also implied that No-rae only said "It's uncomfortable here" because No-rae was the one who was uncomfortable.
However, after No-rae said "Do as you like. Because I'll be fine with whatever you decide", Seol-a realized that No-rae was thinking about Seol-a's best interest, and not her own needs. She probably wanted to take back what she said about No-rae feeling uncomfortable. That's why she said "I'm terrible", because she acted selfishly without considering No-rae's intentions. Or something like that. idk it's just my interpretation so I could be wrong
