I can barely remember anything about my "first". It's really hard LMFAO But if I have to point out a few when I was super tiny I'm pretty sure my crush was:
Nezha... LMAO Hey, instead of western cartoon, all I have is Chinese cartoon so you can't expect too much from me. My love for Nezha stays pretty consistent though, from his cartoon self to his live action self.



Such a wide variety of Nezha LMFAO
Then in my preteen was my anime craze time and I remember pretty clearly my first manga/anime crush
was Natsume Hyuuga from Gakuen Alice.

How nostalgic.
