I finished Alchemy of Souls the other day and although I enjoyed it, I'm sad we only got to see powerful Naksu for only a few minutes in episode 1 lol. Would love romance drama recs with a FL that has some sort of powerful ability n_n

Back From the Brink (2023)- Later on FL gets powers

Behind Your Touch (2023) - FL sees the future by... well... touching butts

Jinxed at First (2022) - FL sees the future

Kiss Sixth Sense (2022) - FL sees the future by kissing

My Demon (2023) - FL ends up having ML power for some time

My Lovely Liar (2023) - FL senses lies

Payakorn Sorn Ruk (2020) - FL sees the future by touching roses

The Last Immortal (2023) - FL stars with little power, but later on she gets powerful

Not exactly powerful, but you may like it:

My Journey to You (2023) - FL is a super spy/assassin

A Journey to Love (2023) - FL is a super assassin 

A Good Day to Be a Dog (2023) - FL turns into a dog

See You in My 19th Life (2023) - FL remembers all her past lives

Who Rules the World (2022) - FL is amazing in martial arts

Agree with Strong Woman Do Bong Soon!  The main leads are absolutely cute, if you can get over the fact that main lead interaction takes first place over plot and characterization of side characters.

Buffy the Vampire Slayer - this is an older western show but this highschool girl kicks ass fighting the supernatural vampires and demons.
