 She fiddles with her fingers and somehow she wants to cry but not in front of him. If she cry, it means she lose and Jungkook will feel his victory. 

 "Well, I hid for someone that I love." She mumbles but surprised to hear Jungkook chuckles.

 "Who will love with this look and remember I've seen enough your body.

 No one will love that." 

  She feels like a stab in her heart, knowing Jungkook is never a nice person. She knew she should trust her brother but Jungkook just makes everything fluttery and she can't contained her feelings.
