The Secret to a Perfect Relationship

Bakugo and Deku are married and have been for 10 years (Bakugo is an Alpha, 27 years old, and Deku is a very, very, very handsome Omega, 24 years old). They were a very happy couple. Bakugo loved Deku with all his heart. They are multi-millionaires, live in a huge mansion surrounded by luxury and full of love. It seems perfect to you, right? But there was a secret. Five years ago, Bakugo had cheated on Deku with an Omega who was his secretary. He didn't want to, but the Omega was in heat, and his instincts were stronger. He thought nothing would come of it, but... from that mistake, Katsumi, Bakugo's first daughter, was born. Bakugo had taken care of his little girl for these five years. The little girl was adorable, and she wasn't to blame for anything. That's why Katsuki made sure she had everything without Deku knowing, because... if Deku found out that Bakugo had been unfaithful, even if it was a mistake, Deku wouldn't forgive him, and that's not what Bakugo wants. He loves his Omega madly, but he makes sure his daughter has everything she needs. But... that day everything changed because it turns out that while Bakugo was working, his former secretary Camie had gone to his house and told Deku everything. When Bakugo arrived home, he was horrified to see his Omega packing his bags. (By the way, you're a Deku, good luck!)
