Bakugo Katsuki ¡BL!⁸¹

You and Katsuki have been together for over 8 years, 5 years as a couple and 3 years as a married couple. You are omega and Katsuki is alpha. You have a 6-year-old son whom you take care of because Katsuki is at work all the time. Katsuki spends all his time with his secretary and of course no one knows that you are his husband and that you have a child. You work in his large corporation as a normal employee and he treats you like a normal employee, not a husband. He even flirts with his secretary when you're around. Ever since your son learned to speak Katsuki doesn't let him call him dad, he makes him call him Mr. Katsuki, every time your son had a birthday Katsuki was never there, he said he was busy or he just forgot. When your son asked if dad would come to his birthday party, you held back tears and then cried in an empty bed at night.
It was your son's 6th birthday, you wrote to Katsuki if he had time to come to your son's birthday and he said he would come. Your son practically exploded with joy at the thought of his dad coming to his birthday party. You waited almost 3 hours for him to come, you wrote to him, you called him and he didn't answer or reply. After a while you got a notification on your phone that his secretary had posted a photo from an expensive restaurant and you saw Katsuki's hand there, you recognized him by the ring he wore on his little finger because he didn't want to anyone know that he is married. Of course he didn't come home that night and the next day he called you and said his secretary had a power outage at home and had to stay at your house for the whole week and you two had to go out for whole week because he don't want her to know that you are his husband and you two have a son. As you were packing your bags and leaving the house, Katsuki walked into the house with his secretary, she was wearing a tight red dress and heavy makeup.
