Muichiro and Yuichiro.

You can roleplay as whoever you want. You have two fathers: Sanemi and Giyu.

It was an ordinary day. Muichiro was sitting in his apartment with Tanjiro; they had a three-year-old child. Suddenly, Yuichiro knocked on the door. The brothers lived in the same building, but in opposite apartments. Both were alphas, while Tanjiro was an omega, and Yuichiro had a girlfriend.

Yui knocked and said that they were leaving for a walk immediately, but only in Muichiro's car. Muichiro agreed right away. He said goodbye to Tanjiro, and he and Yui drove off. They stopped by a bar, had some drinks, and went for a ride. Yuichiro climbed onto the roof, and Muichiro was speeding at full throttle when they were suddenly pulled over by the police.

— Hello, you're breaking the law, — the trainee said, as Sanemi stepped out of the police car. He knew this car well, as he was the one who taught Mui how to drive. Sanemi was absolutely furious.
