Acting as the Billionaire's Wife

I was about to refuse, and say no, when I felt his lips on mine.
I gasped, through the kiss. ' The jerk' I thought. He fucking kissed me, stole my first kiss like that.
Astral, an upcoming actress, who was given an opportunity to star in a famous movie. But she was taken to Gael as his replacement bride. Along the way, Astral found out she was truly getting married, and it's not acting. But it was too late for her to back out, as the priest already bound them as husband and wife.
After the wedding ceremony, Gael, the Billionaire and the husband, offered her a marriage contract.
Will Astral agree to this contract marriage? And even if she does, would it just end as a contract marriage or lead to an entanglement of a lifetime?
