Chaotic in the best way, heartfelt and fun with that Enemies-to-Friends energy between characters.

Here the 2nd couple is playboy x nice guy.

Van is a playboy who dates Farm who loves him. The 1st couple give bad buddy vibes with the friends but enemies to lover troup

I'm only recommending this cz even here the MC's are initally not serious about the relationship and date them for other reasons but then they fall for them

Same leads as this drama. The lead here is also a red flag who casually goes out with the MC but later comes to realise how much he loved him.

Going only on the first ep of Glory - similar story of multiple female main characters, smart ML, conspiracy in Ancient China, enemies-to-lovers trope.

Loosely related through the industry the women are in - tea plantation vs. teahouse.

Good production values in both, great casts.

The main couple of both shows is played by the same actors (Boat & Oat). so if you want to see more of this couple, I highly recommend watching this.
Based on the trailer and the omegaverse setting of Knot, the inmate scenes will probably be comparable to My Stubborn.

Otherwise most likely not a lot of similarities, in terms of story and mood, since Knot is omegaverse with a more serious mood, while My Stubborn has a lighter office setting.

I feel like they both are kind of that angsty romance, with a sprinkle of slice of life and some scandal/controversy/conflict in the picture that majorly impacts the leads life and relationship.
Though, Call It Love is better in terms of quality imo.

Both show reversed gender roles, though for Ye Cheng, the MCs live in a matriarchal society, while in The Cross-Dressed Union, the MCs are both cross dressing and so take on opposite gender roles. Both feature the man marrying into the woman's household as part of a political scheme.

Xu Tong Sheng, a passionate and intelligent young fireman, joins the fire brigade's arson team in order to continue investigating the people he feels were responsible for the deaths of his parents 18 years earlier.

Together, at the request of Xu Tong Sheng, they become a formidable team. Through multiple investigations, this threesome sees that there is more to the arson cases than meets the eye and conspiracies run deep. Can they find out the truth and get the justice they seek before they, too, become engulfed in the unnatural fire?

Sahashi and Natsume form a working relationship as cosmetic consultants at the request of their company, with both consultants being star employees. However, the impolite and disrespectful Sahashi is a big headache for the senior Natsume. What's more, Sahashi discovers Natsume's secret and threatens him with it...

Both leads grow up as semi adopted siblings. The FLs are younger and high spirited, MLs are older and troubled. Both dramas have several year separations between the leads in which FL becomes more mature and ML endures emotional and/or physical trauma before the two reunite.

Both leads grow up as semi-adopted siblings after FL's father/parents feel they owe a debt to raise/provide for the ML. Both FLs are younger and somewhat childish, MLs are older than her and serious. Both MLs have or end up having a major leg injury due to a car accident which causes them to feel they can't be with the FL despite loving her.
