who’s arc is after this one?

I'm guessing it's Somang's sister. The one with black hair and tanned skin, she seemed really off when Somang asked her about school. I forgot which episode it was tho where I saw the scene, I could be wrong though. So far she's the only candidate.

It could also be the guy in the very beginning, with the glasses talking ab the cold

Oh true, I didn’t think about that!
