Signal! The best drama of the year!
Remember – War of the Son
Love in the Moonlight
Moon Lovers: Scarlet Heart Ryeo
@Kar  Thanks!! :)

@ Iwyn  From you on-hold list....watch Ryusei no Kizuna and Koishite Akuma...I loved them!!
@kar you should really start on Love in the Moonlight. It's incredibly good and Park Bo Gum is just amazing!!

@IzzyDramaLover for you I'd really recommend two from your list because they're in my top 5 favourite: Splash Splash Love and Signal. You won't regret watching these two. SSL is really cute and romantic - only 2 episodes in, and Signal kept me hooked until the end :)
@Bongsookie Thanks! I recommend watching: It's Okay, That's Love!
@Bongsookie  Thanks I'll definitely watch them! :)
