Being a typical high school guy, I cannot deny the fact that he was immature, silly and materialistic.
Here, "a typical high school guy" is supposed to refer to "I", which I don't think is what you intended it to be. It also seems strange that you previously mentioned that he's thoughtful and then, in this sentence you say that he is immature and silly.
Plump, short, and my face spotted here and there with pimples, I was definitely not the center of attention especially when considering that the girls in my grade were considered as the prettiest bunch in school and when that the guys had high expectations of how a girl must look.
With western blood in them, my classmates had outstanding looks and they knew it.
Sounds awkward.
Me I , on the other hand had chunky short legs, a completely round face and pitch black wiry Asian hair that scattered all over the place.
I was occasionally baffled by my looks but the "Intensive Beating" made my visual complexities the least of my troubles.
What do you mean by "Intensive Beating"?
I just tried not to face such a problem.
What problem are you referring to?
Hoping to have for a mind-relaxing break and a chance to talk to my crush, a few of us some of my peers and I gathered around one table.
Again, terms like "a few of us" cannot be used without previoiusly mentioning who the "us" are.
Hmmm... This essay does present some intriguing qualities about you, but
Kevin is probably right. Include some aspects that adcoms would usually look for in an admission essay. It's a great essay nonetheless, and I think you can definitely stick with this topic.
