Yeri thought that a promise she made out of her desperate attempt to return back home will soon be forgotten. She will never meet him again anyway. But that's just what she thought. thanks for the trailer ^

It was a game for Yeri. Flirting with her friend Jungkook that is. And she will definitely have fun with it until the guy gives up and lets her win.

Wherein Yeri and Jungkook are just both shy (lol idk how to describe this)
