Based from what I have seen on the forum? Teenagers are not really prone to experiment in music that much and usually listen to mainstream stuff, no matter how un/popular kpop is in their countries. Most people I know who are into Japanese music (or Japanese culture apart from anime) are people that are at least in their mid-late 20s. I haven´t seen you discussing life related matters that much, but when you do, you can hold a proper, very cultivated and serious conversation, hence my guess would be ... hmm, so not a broke uni students trying to be a bit edgy. I have noticed that uni students are often in the position of "keyboard warriors" treating every possible Internet platform as a lecture room where their opinion should be listened to, they are easily offended and often feel like they are saving the world despite the world not being black and white. you ain´t that, you would probably rather step down from the podium and let the kids fight. that is a sense of maturity, I assume.
you can still be funny and entertaining and empathic enough to help people collect their cards and like to talk about music here and there, but only if it interests you.
I know your age, but you definitely come off as youthful minded, fun, calm and interesting. I think it´s actually great to see because at least people will understand that age is truly just a number in many many many aspects.
Not legal aspects ,in that case, age matters, please kids don´t drink.
