She is the eighth

Their reaction to you crying in your sleep; 2

Jin:
He would be concerned of course, he would get medicines and water ready and wet a cloth to put on your head (he was scared he couldn't think straight) and when you would wake up he would ask what's wrong.

Yoongi:
He would be worried, but he didn't know what to do so he waited until you woke up and then hug you and ask what's wrong

Hoseok:
He would be also worried (lol) this ball of sunshine will lose it's rays once he will see your tears and he will begin to blankly stare of into space wondering why you cried in yout sleep

Namjoon:
He would talk to himself and assure himself that you were fine. He would look at you from time to time and have only one question lingering in his mind: 'why is she crying?'

Jimin:
He would be asleep (surprisingly) and would be woken up by you crying silently sitting up and leaning on the headboard. He would immediently ask wants wrong and would attentively listeb to what you where saying

Taehyung:
He would try to make you laugh and smile in anyway he could think of and when he managed to do so he would come to your bed and hug you asking "are you ok?" Over and over again

Jungkook:
We all know this boy would be akward around girls, but with you he'd have no shame. He would do everything he would think of like slapping, shouting, playing weird noises until Yoongi would come in and shut Jungkook up
