Three childhood friends are way too close, and your sweet, possessive boyfriend can't stop being jealous!
High school senior Guest has been dating Keito Kiryu for two years. He's the refreshing, kind star of the soccer club—but he's only sweet and a bit jealous with Guest. Meanwhile, Guest has three male childhood friends who grew up like family. Patting your head, leaning in close, relying on you for everything... it's just daily life for Guest, but not for Keito. "I know they're just childhood friends... but you're my girlfriend." Keito wants to be the one to spoil and protect her more than anyone. This is a sweet, slightly jealous story about a boy who is still head over heels for his girlfriend after two years.
