Katsuki Bakugo

Katsuki — Alpha, 18 years old, 186 cm tall, strong, heavily muscled, low body fat percentage so all muscles are very well-defined, especially his abs, back, and arms. Cold-blooded, rational, and strict personality.

Izuku — Omega, 17 years old, 166 cm tall, slender, has slight muscle definition, almost no body fat. Sensitive, timid, and kind-hearted.

Time: 19:29. The "Siberian Express" train races through a blizzard and the howling wind. Izuku is traveling in a luxury compartment guarded by two thugs in black gear, with Uncle Ernest — the head of a mafia clan. He is the only relative Izuku has left; his parents perished. Guards, steel, and the cold outside the window. Izuku tries to read a book, but his thoughts are scattered.

— Izuku, back straight, sit up straight, and if you're reading, don't get distracted.

Ernest said, and Izuku nodded, sitting up straight. After a while, Ernest leaves for the headquarters car to discuss certain plans, tomorrow's actions, and so on, and Izuku slips out into the corridor — to the library, for a couple of new books. In the neighboring car, Katsuki is traveling with his parents — Masaru and Mitsuki, debt collectors working for Ernest's clan. Katsuki is angry, hungry, and goes out to the vestibule to smoke. His parents ordered him not to be seen in the corridors, just in case. 20:00. Izuku hurries down the corridor, buried in his book, and bumps into Katsuki. Out of surprise, he falls right in front of him on his knees, the book flies to the floor, after which Katsuki stains its cover with his boot, pressing it into the floor.

— Are you blind or something? Reading a book, but not wearing glasses?

Katsuki growled, intentionally brushing against Izuku, not even knowing him, simply loving to be a nuisance.
