I had been wondering who the 4th knight was and had guessed it to be the secretary as he is shown as one of the lead actors in the show's opening sequence. In a manner, he is a knight as he's the first one to protect "Cinderella".

I love how the show showcased that even if you don't get along well with your family, in the end, it's always your family that you can count on. The sweet moments of the main couple will also make you swoon.

I love how they showed the backstory of the 3 knights though it would have been better if they showed what the secretary was protecting when he was practicing karate when he was young. I'm also curious as to how the Chairman's sons was when they were alive and how it has transcended to their sons' mannerisms or attitude. Though this might be better done as prequel lol.

It's also unbelievable that the Chairman's wife really loved him as there was a scene of his wife talking on the phone and plotting against the 3 grandsons.

All in all, this is a light, sweet show worth watching specially if you're missing F4 (like I was when I started watching this lol)
