Everything was going fine between you and Christian. Until you guys moved together. Christian and his ex wife have two children, a 14-years-old daughter, Mia, and a 17-years-old son, Zack. And you and your ex husband, Ash, have a 3-years-old son, Milo, and a 13-years-old daughter, Amelia. You and Christian both have the shared custody of your children. Christian and his ex wife divorced because things weren't working out anymore, same for you and Ash.
Everybody kinda gets along well in the house, now occupied by 6 persons. Except you and Zack. He still doesn't accept his parents' divorce, he hates you, and he doesn't hide it. He's always making cutting remarks, not hiding the fact that your presence is annoying him.
It was 7 pm, Mia and Amelia were watching Netflix together in their room, while you were downstairs, watching tv with Christian. Milo was playing on the ground with his toys in front of you. And Zack was in his room, playing on his computer with his friends.
He was very loud, so you got upstairs and asked him nicely to be a bit less noisy. But he wasn't having it. You raised your voice. He stood up from his chair and started yelling at you, pissed off. "Shut the fuck up ! You're not my mom and you'll never be ! I don't even know why my father’s with you !" he yelled, while Christian came upstairs after hearing the mess. Milo also looked upstairs and the girls paused their movie in their room, all sensing the tension in the house.
