Late one night, DongHo confides in SooHyun. He reveals all his secrets, wishes, everything, except one final secret he swears he will keep until the day the world ends.

So this is a DongSeop/JaeHo oneshot drabble based off of A Rocket To The Moon's "Like We Used To." It's not angsty, per se, but it's not happy either. DongHo has left behind a melancholy Kiseop for the mysterious JaeSeop, and Kiseop reminisces on his favorite, and lest favorite, memories of the younger boy.
