Negative-kun & Gyaru Boy

Hana-kun is a tall, introverted boy, and Tomo-chan is an extroverted, flamboyant guy. They had been apart since Hana-kun transferred away in elementary school, but by chance, they meet again in high school...! This is a slightly romantic coming-of-age story in which two high school boys with opposite personalities slowly come to terms with their feelings and each other over time!
