Ayumu Sakura and Hiro Oikawa are classmates and childhood friends. Ayumu's always had feelings for Hiro, but she's never had the courage to tell him. Hiro's always thought Ayumu was cute, but he thinks of her more like a little sister. When they were young, they were always together, but these days their friendship has settled at a casual distance.
Ayumu notices that her vision has been getting worse lately, so one day she asks Hiro to come with her to the optician's. Hiro picks out a pair of frames for Ayumu to try, and she excitedly puts them on. But when Hiro turns around to see how she looks, an electric shock runs through his body.
She looks adorable!
Hiro immediately falls head over heels for the spectacled Ayumu and asks her to go out with him right on the spot. Ayumu is left completely stunned, but she accepts.
Now the freewheeling Hiro is dating Ayumu, who has no romantic experience whatsoever and freaks out over everything. As the awkward couple make up for the time they drifted apart, their relationship grows deeper than ever before.
