Who's That Long-Haired Senior?

Sol Song has a uniquely quirky taste in men: they absolutely must have long hair. Otherwise, she sees them as literal "stone heads," devoid of facial features. So, when her first love—and the only long-haired guy on campus—shows up with a buzz cut, she's devastated. But as they start to reconnect and emotions deepen, Sol must discover whether she likes Okseok for who he truly is or just for his hair.
