I have a theory (pls dont take it srs) i feel like eun is a lawyer cuz in previous chapters (i forgot) it did say that he wanted to major into law ( also his mother is a lawyer im pretty sure and she goes away most of the time)and law school can take up a few years although be did study abroad it depends how long it took for him to finish etc etc i feel like the girl is either a co-worker or client cuz by the way he looks he looks relaxed and he's smiling too so that might be the case like he were to know the girl yk. JUST A THEORY GUYSS😕 i
