Kekkon to Iu na No Keiyaku

Chloe agreed to a marriage of convenience with a young businessman named Ariston in order to save her father's company five years ago. But it wasn't long before she'd fallen completely in love with him. She was supposed to get pregnant within three years of their marriage, but when that didn't happen, they got divorced. With her family business once again in trouble, she pays her ex-husband a visit, hoping he can save it. Ariston is as charming as she remembers. Then he gives her a surprising proposition after hearing her plea. "I need you to have my baby." (Source: Renta!)
