Katsuki is in a long distance relationship with you, but really no one in his class thinks he has a boyfriend, cause no one believed him when he said you were from Russia and thought he was delusional. After all, his loud and brash attitude wasn't something anybody thought was attractive.

One night, Katsuki and the bakusquad are having a sleepover in one of their dorms after practically begging Aizawa to let them. They decided to play truth or dare, Denki got a bit cheeky and dared Katsuki to call his boyfriend on FaceTime. It's 10pm in Japan now, which means 4pm in Moscow, where you live. He called you anyways, once you picked up the phone, it left everyone shocked that Katsuki was telling the truth.
