"I don't think of us as just childhood friends. "What do you do when you wake up half-naked... next to a childhood friend?! Himari's always yearned for a real true love, but she's always finding her efforts blocked because everyone thinks her childhood friend Aoto who's ALWAYS hanging around her is actually her boyfriend. One day, she wakes up after drinking WAY too much at a mixer while trying to find the boyfriend of her dreams... only to find herself in a hotel wearing only her underwear and lying next to a half-naked Aoto?! "Hold on a minute... Don't tell me Aoto and I... did it?!" He's so childish and unreliable, so for Himari to feel her heart race when seeing him as a man for the first time just seems... totally unexpected! Can childhood friends really fall in love...?
