I'm not emotionally stable right now. Big Hit released a 12 minute video that's meant to be a prologue to basically what happens in I need u.

Anyway some translations:

V: Hyung...I miss our friends (something like that he mumbles its hard to hear okay >< I think he's calling Jin)

Rap Monster: Yah, what are you doing?

Jungkook: Oh it's Jin-hyung!

 If we're together we can smile.

Rap Monster: (Writing on the mirror) We have to live (or survive something like that)

Jin:  (campfire scene) Should we...go here?

Video:

OMG IM STILL CRYING SOMEBODY HOLD ME ㅠ.ㅠ
