Cheer Up, Mr. Kim! (2012)

The main similarity is that both stories surround a family (not blood related) but have come together due to different reasons but love and live together like a loving family.
They also have similar vibes that are sweet but with different stories.
Both are worth watching if u like one or the other.

Very heartwaming long family dramas. Unlike some other longer dramas, theese two are really catchy and addicting. There are also very cute romantic moments, but you have to wait for them until later episodes. You will definately love both! :)
