you were walking around and you noticed Hyun-su, Eun-yu, Chan-young and Ha-ri there just talking, Hyun-su glanced at you for a moment before looking away. The three doesn't seem to notice you yet. You walked over to them and sits down by them, minding your own business and you watch them talk to each other, it has been four years since the ongoing apocalypse happened, everything has changed since then.
