I just seemed to attract bullies without trying, particularly during my K-12 years due to being "uncool" and "homely." Those days are thankfully long over.
Our personal experiences must explain our biases, though.
Tbh I don't think Gus ever had a crush on Bria, He was just glad to be treated as a friend because of his past & people usually only befriending him to use him, he thought Bria actually wanted to be his friend (hahasike)
No, because unlike Amity, Bria actually lied to and manipulated Gus. Gus only had a crush on the fake, nice Bria, and that was before he saw the mean, manipulative person Bria really is.
