Byul and yongsun day by day is like a twins, sometime when krystal and wheein said they're like a twins , yongsun is denied it while laughing, or while grin. Yongsun always make byul promise whenever she tell story about herself to byul. Because yongsun is like had trauma, and yes, yongsun have trauma in the past where she trust that person but that person is telling to other people about story herself. So since then, yongsun always have cold face, arrogant face, because she want the other close to her, make her comfort and the they hurt her. There is like a big wall she build since then. Even she usually tell story with krystal, but there is more story about her didn't tell krystal. Because she feel insecure. But with byul, she is like open her trust to someone. With byul she can express what she want to tell, she can express her feeling, happy, sad, and anger.

Yongsun always feel safe sometimes whenever she with byul, but she didn't tell byul anything she's feeling when she with byul. Because byul is too confident, too self praised. Yongsun can't stand with that. Actually when yongsun praised byul, byul is hide it her blush with her confident, byul know yongsun can't stand with it. 

Always, when the night come, yongsun tell story about a guy who she have been close lately through the phone.
