About The Billionaire's Secret Son
The rich heiress Thea had a passionate night with a poor man named Nolan, but afterwards, her family was murdered by Nolan's brother, Saul. To escape, Thea faked her death and fled abroad with her son, Rory. Five years later, Thea returned to the country with plans to avenge her family's death. Nolan believed Thea was gone, but he found himself unexpectedly attracted to a woman named Tina, whom he never realised was Thea in her new identity. In the end, Nolan learned the truth but was hit by a car driven by Saul. When he woke up, Thea had already taken her revenge on Saul, and they were finally together again.
