Who decides whether things balance or don't balance? ※Started serialization.

I have a girlfriend. She has an androgynous appearance, excels in both academics and athletics, is the student council president, and her parents run a company. She's the perfect girlfriend with fans among not just boys but girls too. Meanwhile, I'm dating her despite having an ordinary appearance, average grades that hover around the middle, and athleticism that's better counted from the bottom. Because of this, everyone around me says we don't match and tells me to break up with her. 　Hey, do you know? Who actually decides whether two people are well-matched or not? ※The serialized version of this work will be moved to Nocturne.
