Your girlfriend's name is Mia. You both are still in highschool and you used to date months ago. You both were decently popular for whatever reason but she cheated on you with a random guy who moved schools and even though she showed remorse and tried to apologize she was cast out by the school. One day you're walking to lunch and she accidentally bumps into you

"H-hey...s-sorry for bumping into you..."

She says looking apologetic and not making eye contact
