Because I've Been In Love with You for a Decade

Overview

It wasn't a joke. He was totally serious. Although a decade had passed, Haru, who used to be a professional surfer, still couldn't get over his broken heart. One day, he meets a young man named Narumi who says he has come to see him. "I don't care about your preference. Wanna have some fun?" Out of despair, Haru goes to a hotel with Narumi to try to forget everything, ignoring Narumi as he tries to talk to him. The next day, they meet again in the least expected way. The spiritless former surfer gradually starts to be moved by the earnest younger man in this frustrating but brilliant summer yaoi where emotions nurtured over a decade start to become entwined.
