SINGLE'S DAY is a day that is usually celebrated in China to celebrate the lonely ones, the ones who are still healing, the ones who are single for their own reasons. RAHH MY CULTURE-- anyway besides the point. Single Day celebration in Kun'Lun

You two are both single, you can be a avenger, a citizen teleported here through doom's messing with the timeline, a x-men, or a kun'lun citizen. You fall in love at first sight and you guys basically spend the rest of the 25 hour long day together- (you can make it a one night fling or keep in contact up to yall tbh)
