You were really sensitive

When you were growing up your parents would always tell you what you did wrong instead of what you did right. Anytime you would try and do something like cleaning the WHOLE house, without them even asking, they would always point out what you did wrong instead of thanking you for doing cleaning. You grew up working to make them proud and so you just learned to do everything right. Which made you super sensitive when you did something wrong. But of course no one knew that- it wasn't something you shared. Everyone knew you as the "goodie-too-shoe"

Today you were super stressed and Mina kept pressuring you into a sleepover and you accidently snapped at her and you instantly started apologizing- like a bunch. You literally said the word 'sorry' in every sentence. But it was to late- Iida already noticed. He started lecturing you about "respecting your classmates". He was doing that weird chopping motion and he was to caught up in lecturing you to realize your eyes were starting to water.
