How can he really think about his feelings if mr lee is just going on dates with other person, like sunny is feeling worst with that! Manaacass
They are both feeling confused and hurt. Mr lee did that because he thought sunny only used him as replacement, he was also hurt when sunny didnt answer the question whether he likes him or not.
I think sunny really need some time to think about this. I mean like, he can't even admit that he likes mr.lee unless its in his wet dreams lol.
Anyway, Yoo is like the friend that we all need. Sanaol HAJAHAH
