i want to know the name of a Korean drama which i watched a few episodes for

basically the female lead is a single mom who has an illness or cancer so she wants her son to connect with her ex husband who got remarried and has a daughter too

sorry if this is vague but thats all i remember (i think the title had mother in it but not 100% sure)

Mama

synopsis:  A single mom who has been only focusing on making money and achieving fame is suddenly finds out she has a time-limited life. All her life, she has been neglecting her only son so she now wishes to spend the rest of her lifetime for him finding his family before she leaves. She plans to reunite her son with his birth-father so he can live in a stable family environment, but the father is already married to someone else. Mama is a story of 6 months of motherly love and sacrifices that is told by a terminally ill mother.
