it would basically be his first girlfriend/high school sweetheart but i'm open to having her not be in school if that's the case! they could have met somewhere outside of the school and she was basically his first real relationship. we could say that they are still close friends since regardless of the breakup, benjie wouldn't want to lose her. if that doesn't work, they could have met the same way outside of high school and started up a friendship and they're still close today
