shy girl/boy
He wanted to break (him/her), he so badly wanted to make everyone know that he was the biggest heartbreaker. He already was but that didn't meet his standards. He knew (he/she) were known for being the goody two shoes who is smart enough to not let anyone play with their heart, but he wanted to prove the world wrong.
He wanted to be the one to prove (he/she) was weak, unintelligent, unwise.
But things went all wrong, he fell in love, he broke his number one rule. He didn't know how, but he did. The tables turned even more when (he/she) found out what he intended to do, cause at the end, he got his heart broken.
Not the shy (boy/girl).
