Leaving with the Child, the Movie Star Panics

[Forced love + showbiz + occasional bouts of madness + an actor who fights, schemes, plays innocent, and acts aloof]

[Both leads are each other's only partners + rekindled romance + the male lead is a nasty jerk early on, then fights for her, gets jealous and insecure, and begs humbly for her love]

The heroine is an illegitimate daughter of a wealthy family. Her father has a son with another woman, and her mother has a daughter with another man.

Because of her past, she chooses a relatively dangerous line of work: bodyguard.

During a security assignment, she accidentally saves an award-winning actor. He has been drugged and sleeps with her. She runs away before he wakes up, and since he doesn't know who she is, he spends a long time searching for her.

Despite having no experience, the heroine gets pregnant. Unable to bring herself to end the pregnancy, she gives birth and plans to raise the child alone and live a quiet life. But her mother becomes seriously ill, forcing her to return to bodyguard work, and the actor starts pursuing her again…
