A Girl & Her Guard Dog

Isaku tries her best to get over Keiya, and she finally starts to make a new friend. But when she sneaks out to karaoke with her new friends, she learns that not all friends are what they appear to be.

Isaku is frustrated with Keiya when he doesn't even try to pass his tests at school. They agree that she'll give him a reward if he passes his next make-up exam, but the reward he asks for is nothing Isaku could have expected.

Isaku, Keiya, and their class go on a trip to the beach. Isaku continues to grapple with her feelings for Keiya, but there seems to be danger lurking around every corner lately.

Isaku is kidnapped by members of the Kodan-gumi, and Keiya has to save her. Although Isaku's summer break comes to an end, Keiya tries to make up for lost time with an in-house summer vacation getaway.

Isaku is super bored after finishing her summer break homework, so Keiya suggests going to a festival together. Is it a friendly outing, or is it a date?!

Isaku and Keiya meet Mikio, the grandson of another yakuza gang's boss. They're not fans.

The class practices Romeo and Juliet for the culture festival, and Keiya loses his cool with Mikio. Isaku has after-rehearsal practice, and someone unexpectedly shows their true colors.

With Keiya unable to act while Mikio has a knife at Isaku's throat, it looks like both Keiya and Isaku are at Mikio's mercy. But when Mikio attempts to sexually assault Isaku, she doesn't play the role he scripted for her.

As Mikio exits stage left, another wrinkle in Isaku and Keiya's relationship enters stage right.

After what Keiya told her, Isaku needs to make a decision about what to do next. But who can she go to for advice?

Isaku works up the nerve to confess her feelings to Keiya, and not only is Keiya's response upsetting, but he also almost kisses another girl at school the next day. Isaku's friends try to give him advice on how to rectify his mistakes.

Isaku recounts her life and the past year with Keiya. Although things are awkward at first, the two are able to make up.
