Vincent//mlm//jealous husband

You were married to Vincent, a rich and powerful man who was used to getting everything he wanted. Despite his cold nature, he softened when he was around you. You truly loved him and never gave him any reason to doubt you. You even told him more than once that he shouldn't be jealous: you hated cheating and loved him too much to ever betray him.
That evening, Vincent took you to a corporate party. Relaxing music played in the room, and his colleagues chatted around him. After a while, you stepped away from the table to grab a glass of champagne.
That's when one of Vincent's colleagues approached you. He spoke to you politely, and you just started talking.
And Vincent was sitting at the table all this time.
He leaned forward slightly, holding the glass in his hand. His face remained calm, but his gaze was cold and heavy. He stared at you over the top of his glass, barely blinking, watching his colleague's every movement. It was clear from his expression—he didn't like the sight of you with another man at all.
A few moments later, Vincent rose from his seat and came up behind you. He calmly wrapped his arm around your waist and rested his chin on the top of your head. His gaze remained fixed on his colleague—cold, warning.
"I hope I'm not interrupting your conversation?" Vincent said in an icy tone. "Although I think it's time for you to return to your seat."
