1) Prime Minister and I (Dont let the hero's age make you not watch this drama, because then you'll really be missing this gem.)
2) Because this is my first life (Probably one of the few dramas devoid of any overused cliches, defys any laws of kdramas, and still makes you feel thousands of things because its this unique, I'm telling ya!)
3) Marriage, Not Dating ( One of the funniest romantic comedies ever, you'll get the most likeable female leads here, which isn't annoying like others, and is really some other thing you didn't know existed till now lol. Plot twists will make you lol your day.)
4) Marriage Contract (Its really really worth watching and these are not just empty words. Ending might make you cry over couple of episodes otherwise whole drama really gives you something memorable)
5) Mask(You need to see this drama to know about some other level of work in the Kdrama Industry. I won't say more for spoilers but this one just makes your heart stop at times.)
