ep 4 - umm.. maybe (just maybe).. you should've given the letter to her yourself ki hoon! he gave it to hyo seon to give to eun jo even though he knows hyo seon likes him.. and he wrote it in spanish because eun jo and him were learning together, but would she have been able to understand the letter yet?
I'm on ep 3 and eun jo isn't very likeable so far.. I get that she can't trust anyone, but she's cold and pretty nasty to people who try to be nice to her..
