Must watched/most popular K-Dramas

My recommendations for must watch k-dramas are: 49 Days City Hunter Secret Garden You're Beautiful All of them have at least a little bit of romance.

If you want to talk about popularity than you have:
1.Reply 1997(almost everyone around here have seen it)
2.Innocent Man(one of my favorites..but is melodramatic so take note)
3.You're Beautiful(seeing that you've watched Heartstrings I think that you'l be pleased with a drama that has both of them in it, not to mention its popularity)
4.Boys Before Flowers(I really can't describe the popularity of these one...just take in mind that its soundtrack list still appears on some variety shows)
5.City Hunter(really good)
6.Dream High(is another popular drama with romance in it...you may say that it was the first drama with only idols)
7.Coffee Prince(this is a drama that had one of the most popular on screen couples in dramaland...some call it a classic but for me is really a must seen)
8.Goong(popular drama is little said for this one)
9.Iljimae(if you want to try a historical one give this one a try...even if it isn't the best one out there every historical lover have seen it)
10.Full House(I really loved this one...it's a classic)
