Ai's gang - gorgeous guy-friend So, his best friend Kato, and Mina, a ganguro - gather at her place for a study session. But guess who tags along: So's ex, Chiharu, who's now a "student teacher" and out to get So back! Chiharu digs up Ai's old diary and runs off with it - can Ai keep her from exposing her embarrassing past?!
Later on, Ai gets offered to model for a popular teeny bopper magazine, but a trip to the beach for the photo shoot turns into a standoff between best friends So and Kato. Who should Ai root for?
And then Ai takes it upon herself to take revenge against a guy she believes dumped Mina last summer. But Ai may have gotten things wrong...
