Petty as it is, the hair extensions were my one complaint about this show lmao. And they're finally gone! She looks so good.

I would say it's copy paste on purpose. Like an intentional pop culture reference. Kingsman was oddly popular in Korea.

I thought of two suggestions.
Knight Flower: The FL is a a widowed vigilante in Joseon and the ML is an uptight policeman. She's a better swordsman than him and often outsmarts him or saves him. There's also an age gap. Though it's not an explicit plot point, the actress is 10 years older so its always apparent.

Queen of Tears: Ice cold chaebol FL who is married to her very soft subordinate. Warning, their relationship is very toxic but on purpose. It's a black comedy.

Thanks for the list! I visit quite frequently to check for updates. I've gotten quite a lot of good recommendations from here.
