Like I said in the title, I'm looking for some thriller/ crime dramas, possibly with some kind of psychological twist. Bonus, if it also has some romance. 

Something like Gap Dong, Ouroboros, Maou, etc

Thank you in advance ^^

I didnt watch those you mentioned but from your description, I'd recommend :
- I Remember You
Love Me if You Dare

It depends on what you consider a psychological twist but you may also like :
I Hear Your Voice
Pinocchio
Cruel City

I Remember You

Pied Piper - no romance, iirc, might've been a littl

Reset - no romance, but a school girl looks exactly like the male leads dead gf, also the male lead can hypnotise ppl.

Wanted - no romance

Secret Investigation Record - no romance. Pretty much x-files set in historical times with really cool cinemagrophy, imo.


I Remember You and Reset are probably the only two with some psycological stuff, at least from what I remember.

I haven't seen these ones so see for yourself if this is what you're looking for

 
These ones are more psychological than crime:
If you haven't already seen it, then I'd suggest "Liar Game" both the Korean version and the Japanese
Also maybe "Mask" (it definitely has romance in it)


Hope you found something that you like~ Good Luck! =)
