Female Leads strong & smart- got such a compelling personality because of character development & bold actions.
Blood line sisters -family really close storyline in the beginning sometime in the middle of the drama they separate.
One smart & one deceiving (TFL is physically strong with her martial arts skills but gets envious of her sisters intelligence & character.)
Palace drama- both male leads have a superior position towards FLs

Some similarities basely involved "theres always a time for everything" , background difficulties, some toxic and obsessive second leads syndrome, and mainly meeting at the wrong time but making up for it later on (character development).

Phoenix includes love scenarios moments that both main leads & second leads are included in (eg : FL loves ML but have conflicts & nearly create & fall for second leads.) The second leads also have something they hide about their occupation eg & background. & the second male lead is willing to get the female lead even in their bad condition

Both sisters love the male lead & also the sister is jealous of the female lead. Both female leads take revenge and also is badass.
