Help

I'm searching for this shoujo manhwa where fl is a mistress of ml and ml treats her bad. Use her for Suggs. So she run away and there she gave birth to a boy. Somehow ml finds her and ask her to be with him again. BTW fl loves writing. Her uncle is a writer. She is blonde with green eyes and ml Is dark navy hair colour with blue eyes and their son is similar like his dad. I can't find the name.
