Surrogate Wives For Billionaire

Her sister ran away with another man on her wedding day, forcing Danera Gillard to replace her twin sister in marriage to Zayn Wilde, a successful but heartless young billionaire and businessman.
"Don't get your hopes up in this marriage; you're just a substitute until I find Doriane," Zayn whispered in a cold voice in Danera's ear.
"I understand," Danera said softly and hoarsely while planning how to escape. Then, her twin sister returned and wanted her husband and marriage. Doriane and the Gillard family trapped Danera in a scandalous affair that earned her the scorn of everyone.
"You want my husband? Fine, take him back! He's a bastard of a husband."
Danera swapped places with her twin sister and ran from the authoritarian Zayn Wilde with a baby in her belly. Five years later, she returned with a cute little boy and avenged her twin brother and the Gillard family.
....

"Sir, the young lady is back." The secretary reported to Zayn in a hotel room. Doriane leaned spoilt on Zayn's arm and stroked his chest.
"Young Madame? Honey, you haven't divorced my sister yet?"
"Not yet. Since she's back, I'll divorce her soon." Zayn replied coldly and indifferently while taking a sip from his glass of vodka.
"But sir, the young madam returned with a little boy who looks much like you."
Zayn immediately pushed Doriane and stood up.
"Hurry up and get the child and do a DNA test."
"What about Young Madame?"
"We're not getting a divorce!"
