Isaku gets into the high school that she wanted and is excited to finally meet classmates who don't know she's the granddaughter of a yakuza boss. Unfortunately, her family member/crush/bodyguard decides to attend school with her.
In an attempt to get rid of her feelings for Keiya, Isaku meets a classmate Tamaru. However, her attempts to get closer are constantly interrupted by Keiya, who won't leave her alone. Things get worse when Tamaru invites Isaku to karaoke.
Isaku persuades Keiya to study more. As a reward for passing the tests, Keiya requests to spend a day with Isaku which only confuses her feelings even more.
After witnessing Keiya's life being threatened, Isaki realizes that she shouldn't fall in love with a yakuza member because Keiya might disappear right before her eyes any day.
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?.
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.
