They are both based on the manga "Hana Yori Dango" (Yoko Kamio) and there are many scenes in F4 Thailand that are taken at the same background like Meteor Garden 2001, such as Thyme and Gorya ars trapped in the fire escape just like Daoming Si and Shancai did, and that Gorya is bullied physically by her schoolmates such as Shancai was.
And also MJ (Nani) totally has the same vibes as Meizuo (Vanness Wu). They are the only adaptations of Mimasaka Akira that are totally the same as the manga, it's like they both came out of the comic.

theyre both cute little office romances and i'd say they have pretty similar aspects of the push and pull for a relationship

Both are very similar
The FL can't be with the one she loves because of the obsessive love of another men.
There is a lot of betrayal, court problems and power struggle in both.
In KW you recognize the enemy because he is the main character, but in PS you only gonna find who he is a bit later.
The Princess Silver is somewhat lighter in the beginning, but it turns out very painful.
