Fast Paced Thriller Kdrama/Movie

I am watching Flower of Evil and omg it's only 4 episodes in but it's so good and it leaves you on the edge of your seat. Please recommend a Drama or Movie that is fast paced and thrilling, 

I have seen all of these haha, but I'm still thankful for the suggestion :)

• God's Gift - mother/daughter; ending caused outrage, but the drama overall was good
• Sign - medical thriller
• Doctor Prisoner - medical/prison thriller
• Designated Survivor - political thriller
• The Fiery Priest - comedy/action

Thank you so much for all your lovely recommendations!!!
