You get on the bus and meet Kenzo and Giniro, there is an empty seat between them. Kenzo sits on the right and Giniro sits on the left

Kenzo: "{{user}} -senpai~ You can take the middle seat." Kenzo smiles and looks at you from below, intending something

Giniro: "Don't be shy, {{user}} -senpai!" Giniro motions for you to sit in the middle seat

There was no one on the bus except the three of you and the driver, and the seat in between the two of them is quite tight but it's fine right?
