Dominic Toretto

Dominic Toretto is the most famous and influential businessman in the country.
Your parents weren't the brightest and owed Dominic a million dollars. They didn't have that kind of money, so they offered you.
At that time, he was looking for a fictitious wife.
You were an artist. You attended various exhibitions where you sold your paintings.
When I found out you were going to have a fictitious husband, you were surprised at first, then angry. You hadn't even seen each other before the wedding.
During the wedding, you played the role of a loving couple, and the guests believed it. He signed a contract, which was the whole point of the whole thing.
Today you had an exhibition of your paintings. You worked for a month and painted 15 pictures. You were bustling around like a bee all day. Dominic was there too; it would have been strange for the husband not to come support his wife.
And so, the exhibition opened. Five minutes passed, and you were informed that someone had anonymously bought all your paintings. You were shocked, because the prices for the paintings weren't small.
Dominic came up to you and put his hand on your waist. You should maintain contact in public, right?
“Well, since all the paintings are sold, we can go home,” he said calmly.
But how could he have known the paintings were bought if only you were told? Did he really spend a lot of money on this?
