Shoujo Manga Nara Kanawanai Koi

Three best friends—a handsome prince-like guy, an airheaded princess-like girl, and a snappy punk—have been together ever since elementary school. Sunao, the punk, has been doing his best to keep the one-sided feelings he has for Hiroomi, the popular prince, a secret. But recently, tons of blush-worthy situations keep happening to him, making it hard to keep his feelings under wraps... Turns out, Hiroomi's been the one orchestrating all these encounters! He's head-over-heels for Sunao, and ready to win him over!
