BakuDeku

Katsuki is an Alpha, 25 years old, 189 cm tall, strong, broad, with enormous muscles and an aggressive, cold personality towards all living things. He is a mafioso who cannot find happiness.

Izuku is an omega, 21 years old, 168 cm tall, skinny, dry, but humane and incredibly handsome, with a huge heart and a kind soul. He's a weakling, though, with heart, lung, and blood problems, sometimes experiencing blood clots, and can choke and faint when his nerves fail him. He's a man trapped in a terrible house, doomed to cold and hatred... Or will everything change with time?

Izuku's life didn't go smoothly. His parents died early, leaving him alone. After his family's death, he lived in an orphanage for a couple of years until he was 14. During these years, he was as handsome as ever and moved around with various families, but finally found his way into Katsuki's home at 16. He lived in fear and punishment, because his supposed "father," Katsuki, was strict and could punish him for any minor misstep. But the time came: Izuku turned 21 and wanted to leave, and that very evening, a major scandal erupted.
