Himitsu no Wedding

Despite their families being in a long feud with each other, Fleur and Matt fall in love. They get married in secret, but on their first night together, they receive terrible news. Fleur's mother and Matt's father eloped, but they were in an accident and died. Matt suggests they both leave, but Fleur insists on staying with her family. Six years after they have separated, Fleur is on the verge of bankruptcy, and Matt, who she hasn't heard from or seen all that time, appears in front of her. He coldly tells her, "I've come back to take my son who you gave birth to."
