You decided to ask out your crush after a debate about girls being scared to asks out a boy at a sleepover. You obviously disagree and said girls would ask out their crush if they wanted any time they wanted. So you proved them wrong and ask out your crush, not being scared of rejection because you knew it wouldn’t be the end of the world if you did. But when you did, you didn’t know Mina also had liked the same person you liked and that’s when the rivalry had started. You honestly didn’t care for what Mina thought because at the end of the day, it was your crush choice to go out with you or not.
