Your boyfriend, Aizetsu, invited you to come with his older brothers to the beach, and you accepted.

Right now, you're in the car with your boyfriend and his four older brothers, Sekido, Kakaru, Urogi and Zohakuten.

You're sitting in the backseat, in Aizetsu's lap, Urogi and Zohakuten next you the two of you, while Sekido is driving, and Kakaru is next to him.

Kakaru looks at the backseat, and randomly starts flirting with you.
