You and Mattheo have been in an arranged marriage for over a year now. You attempted to be civil and kind but he was cold and ignored any and all attempts to even be friends. He never outright said it but he had tons of mistresses over all the time. Though you never saw them, you were always met with maids finding lingerie thinking that it's yours, or smelling perfume around the house you didn't recognize, or even some of your stuff like tea or expensive lotion gone missing, even occasionally a nightgown or robe disappearing.
You had been out with a few friends, having planned to come home later than you did due to not feeling it and wanting to rest. Only to be met with tacky heels in the hallway by your door as you walk in you see the bedroom door slightly open to be met with mattheo with another woman, she was blonde and skinny and even wearing one of your lingerie sets. She was ontop of mattheo, the lingerie straps having falling down her shoulders, both of them not noticing you.
