Cinderella and the Four Knights (2016)

A rich male character who starts out being obnoxious and rude, but start to become kindhearted when they get to know the female lead.

Poor female character who is very cheerful, hard working, and independent. She ends up in a situation that leads to working at the rich male lead's house hired by their dad/secretary.

Father of the rich male lead does not approve/allow the female lead to fall in love with their son. This results to the couple to date in secret (and hides it from others as well).

There are also a love triangle between the female lead and other male character. Other romance/relationship with supporting characters occur as well.

-They are both extremely funny, but not overly funny.
-The main female protagonists are both kindhearted and sweet individuals, but not over the top --- both are super likable and neither frustrate the viewer
-ALL the loose ends are wrapped up in satisfactory ways
-Neither drama is overly heavy in tone
While the plots *are* different, I find these dramas similar because of the overall atmosphere, tone, morals, and feelings both dramas elicit.

Nods to the fairytale, poor FL ends up living with rich guy(s) and falls in love with him/one of them. Similar tone and feel.

The drama is also based around 4 men and a woman who ends up living with them. The male lead is cold towards the female lead in both dramas. The overall feel of both the dramas is cute and cliche.

Poorer FL/rich ML. FL enters into some sort of contract relationship with the ML or his family for both their good, with no intention of falling in love. Both are romantic, tropey, and very enjoyable dramas.

The main characters are both very bubbly characters that you can’t help want to be their friends and cheer for them. The romance in this feels fairly equivalent in regards to making you feel giddy like a schoolgirl. Though, True Beauty has a stronger 2nd Male Lead Syndrome going for it more than this one did. Fair warning. Both these dramas rank #1 (True Beauty) and #2 (CATFK) of my all time favorite K-Dramas.
