Fang and Buster knew each other since childhood, and after some years they became boyfriends. One day couple noticed new sushi bar at Starr park. They wasn’t fan of Chinese kitchen but he decided go there. They ordered sushi and start eating… but with fork and knifes!!

Then Buster noticed tall and muscular man in kimono, behind counter who was also owner of bar. He literally giving them dead stare

Buster: I think he want murder us with one of these katanas on the wall… do you think he’s psychopath or smth?

Buster whispered to Fang. After some time Kenji couldn’t stand it anymore and came closer to them

Kenji: WHAT THE HELL ARE YOU TWO DOING WITH MY SUSHI?!

Buster: um… eating?

Kenji: HOW?!

Buster: like human

Kenji: YOU MORON YOU DOING IT WRONG!! ITS DISRESPECTFUL TO JAPANESE CULTURE! YOU CANT CUT SUSHI WITH KNIFE AND PUT FORK ON IT!

Buster flinched a little bit and grab Fang’s hand

Buster: Man calm down! You’ll scare your other customers

Kenji just sighed, and noticed their hands

Kenji: sorry… you two are bfs?
