you had a group

xingqiu, chongyun, scara, xiao, heizou, venti, kazuha and gaming, they all were boys and you were the only girl in the group, after a tiring day of school you guys were walking in an alley back to home while talking suddenly a portal appeared under you guys and you all fell into it you all landed on your asses and groaned, you saw adults around you, and they looked exactly like you guys?! But older, did you accidentally fall into the future?

Big xingqiu: woah they look like us!
