Ok, so Im trying to remember the name of a drama, and these are the details I know: The main character is a older male, and has a son, whom he lives alone with. The Lead Heroine is a younger women, whom I believe calls the male lead by Ahjussi, and if I remember correctly, eventually turns out to be the Step Daughter of the male leads ex wife. I believe the male lead worked in a restaraunt, but Im not sure about that one.
Thank you for any help or time spent on this.
