Hi All,
I too have forgotten the name of a drama that for some reason isn't in my watched list.
FL lives in the middle story house (?), 2ML lives in the rooftop (?) house. He is now a psychologist (?) but once upon a time worked construction. He met FL & FL's mother when a building he worked on collapsed; mom & then teenage daughter were handing out food, drink, etc.
ML's grandfather owns the construction company that was responsible for the building collapse.
Thanks for your help!
