I honestly can't think of anyone off the top of my mind that I think describes me. There are so many character but i never thought about who I am, you know :/
Because this seems like an interesting thing, I'm gonna let you or anyone else decide who I might be like!
Here are my traits:
I'm an asian male who is kind of short (5'5''). I'm definitely overweight but I don't look my weight, maybe a bit chubby. I use to play AM football so I do have a decent muscle mass (otherwise, I'd be really fat for my height XD). I have glasses and typical asian hair (the spiky one).
For my personality, I am generally kind of reserve and hold back a lot of my thoughts. I am generally seen as a nice guy but can get really angry when I get past my tolerance point (which imo is pretty high). I use to be a closet otaku since I thought it was seen as a bad thing but now I am much more open about it. I feel like I am a bit awkward when I first talk to people but will get very friendly once you get to know me. I used to have a inferiority complex until I gained a lot more confidence from being around my friends with their support.
Based on this, the first thing I thought of was Kurita from Eyeshield 21, mainly because of football. He is really nice and tries very hard at something but has a weakness in the sport that he thinks drags everyone down (in my case, i think my height does). He can be scary but only when he needs to be and is generally a fun guy.
Sorry this post is long but I thought it'd be interesting this way. Feel free to leave a suggestion for who suits me and I will definitely check it out!
