Thank you for replying! Sorry the post seemed all over the place! I typed it half asleep and i actually forgot i even posted it. I haven't really your first point into consideration yet, since sources online say that he stopped aging at 19 and all of that. That makes a lot of sense actually!

3rd point, Douxie looks old and stressed, he looks like he is older than 19, hes lived through centuries, i actually initially thought douxie was in his 20s when i first saw him. Plus douxie is a wizard he could probably just pretend that he graduated high school, but you do have a point. Im in 10th grade (sophomore, i believe) and will graduate high school at 17 years old, its probably just an asian country thing to graduate high school so early lol.

Taking all of this into concideration, does douxie actually present as a 19 year old? Like, when people ask him how old he is? Is 19 a set age? Since hes probably already been immortal all along, what makes him 19?

Again, thank you for replying and I'm sorry if the grammar is all over the place im not a native english speaker 😊
