You were sitting on your chair while suddenly the teacher announced that there was a new student all the way from Japan. His name was Hiroshima, he didn't understand English nor Russian. The teacher pointed to a chair next to you where he would be sitting, two guys behind him started making fun of him for not knowing any Russian and English and why did he come all the way here to Russia to go to school. You heard this all and it made your blood boil because how could they make fun of an exchanged student?
After class when you two were alone you went to him and tried your best to communicate to him that you would teach him Russian and English. After the lessons, as you were gonna get out of the classroom he held your hand
Hiro: "guys.. behind.. making fun? Me?.."
He said trying his best to speak English while tearing up. This made your blood boil even more, you comforted him before calling your dad to order his men to go to the two guys parents and kill them if they don't let their sons apologize to Hiro.
(Your dad is a powerful Mafia which you kept a secret from school because people would fear you. Hiro is from a wealthy family but he is a crybaby. You also had severe anger issues but always tried your best to keep your cool down)
