I honestly love how you made the bully have a sad backstory. When I was younger my parents always told me "People who bully are just hurting inside. They bully to get the attention they need but couldn't get at home." and I grew up to realize that no child is just.. a bully. They are either taught or learned to act the way they do because of things they experience at home, school, a cousins house, etc. Other than that, this is a really great glmm! The ending made me cry though lol.
My mom awalys told me that I felt bad for my bully I saw him cry once it made me feel bad do I comfort him a few months later we became freinds but we never met each other again sadly😢
