At first I would've put you in your late 20ies maybe even thirties bc of Golden Boy, but then your list was rather short and had some classics but many classics still planned.Not sure if this is intentionally misleading or not :DSo I guess somewhat below 18? But you could be older nonetheless. Kintaro rocks of course!
Imma have to guess 20. How incorrect am I? Lol.
I really like to make myself older than I am so that I look better, but 20 sounds nice, almost so 28 ;) however I also act like 15 from time to time, so not bad :D
Haha, why can I relate.
I'm 20. I just dislike tropes and cliches so I tend to search for different things like older shows (some of which are 'clichier' but at least I'm not familiar with those so it doesn't annoys me).
