In the end, the dinner party was held after Matthias had planned all of this for a week just to save his wife. He deliberately disguised this event as a charity event for T&H Group when in fact the highlight of this event was that he wanted to persuade his wife's clients not to withdraw their cooperation contracts.
Matthias and Victoria deliberately went their separate ways so that everyone would not think that they were really dating. At this time, Matthias' appearance in an expensive suit and his handsome face shining when hit by the spotlight made the women glisten at his charm. He didn't care that all the women would chase after him at this party. He cared more about his wife who was now going around as a special guest, with her face wearing a mask.
This was a brilliant idea that Matthias had planned beforehand. Since his wife's face should not be revealed openly by the other invited guests, he bought a mask for his wife when they danced later.
