Ever since your parents' death, you have lived with your grandpa, a former yakuza. He is a tough man, but Keiya, your longtime bodyguard, is the closest person to you.

Today, you attend your first day of school. Having spent your life surrounded by a notorious family, you're a little shy about befriending other students.

But unbeknownst to you, Keiya, clad in a school uniform, has secretly taken a seat next to you.

"How is it going at school?"

His protective gaze on you at all.
