it has the enemies to lover trope like meteor garden where the girl is poor but tough and the guy is a rich spoiled brat with issues of his own who is mean to the her but he eventually changes to become a better person thanks to her and both fall in love with one another and face obstacles to be together. its a slow burn and bickering between the two.
I know that those two dramas have very different plots but there's still something similar about them: the main female character because they both are nice girls interested just in work (they have many jobs) and not in romantic life (they don't really show their true feelings) also they both have a family member with disabilities (Eun Sang's mother/ Eun Sung's brother) and, what a coincidence, their names sound similar. ^^
Both dramas center around a kind hearted young lady desperately trying to survive on her own while caring for a young family member. Both end up homeless, but through unforeseen circumstances, end up being taken into a family of well-to-do restauranteurs. Both learn how to make food that touches the hearts of their customers.
