yes! but this part you're talking about is in the future of the story, the chapters we're reading rn the boys are still in middle school. i'll leave a link that explains better about the timeline: https://zhanxixis.tumblr.com/19daystimeline

I'm so sorry i couldn’t find the links but all the arts are from the original author who posts on her weibo and twitter.
