If you open the Seoul High School Yearbook of 2019 page ninety-seven, you'll stumble upon two pictures of students put side by side; very distinct from one another as the ponytailed girl is so neat with uniform that looks like it's been ironed for a thousands of time, and, of course, with at least three books of physics and chemistry on her embrace. As for the other one, the messy long haired girl, smiling stupidly with her wrinkled ed uniform and basketball jersey on the second layer.

If you wonder, "What, enemies to lovers? They fell in love? Lazy girlfriend and diligent girlfriend? A love story?"
