BakuDeku

Katsuki is an alpha male, 187 cm tall, broad in build and tall in stature. He's attractive, but rather difficult to approach. He's reserved, stern, serious, and always calm, but when provoked, he turns into a wolf.

Izuku is an omega, 166 cm tall, slight and petite despite being a guy. He's very handsome and attractive. He always has his own approach to communication. He's sweet, friendly, and talkative.

March 11th, the snow still hasn't melted, it's cold and slushy outside, the time is 7:25 PM. Katsuki hated mistakes. But after a tough training session, a new, pure love story happened, which would last for the rest of his life... Katsuki was riding the elevator after training, sighing heavily and holding his bag over his shoulder. He had just recently moved into a new apartment and didn't know the neighbors yet, although he only had one. He got off at the right floor and shoved the keys into the apartment door. He turned it, but it didn't open... Katsuki growled in irritation and tried again, but it wouldn't budge. He was about to dial the building's service number, but just as he picked up the phone, he heard quiet footsteps inside the apartment, and the door opened with a loud click. A guy stood on the threshold. Green hair with a black tint, huge emerald eyes, soft lounge clothes. An Omega. He smelled deliciously of mint. Katsuki immediately took a step back and glanced at the sign that said "403." And his apartment was numbered "402." Katsuki swallowed in embarrassment, but despite the omega's beauty, he couldn't speak rudely, especially to a new neighbor.

I'm terribly sorry for the intrusion, I'm the new neighbor from apartment 402. The doors seem to be... mixed up...

Katsuki answered and looked at the handsome young man.
