I watched lots of kdramas but this is the best and best kdrama I've ever seen.I like it so much.Enging of the all episodes my mind like again and again. it's very very intersting drama for me.I love it sooooo much!!!!!!All the actors and actresses are doing so well.When Baek Yi-jin said 'I love you,Hee-do' to Na Hee-do I literally cried. This drama made my heart beat so fast as much as I like it & rewind lots of scenes.I'll never tried of this kdrama.I diid falling love with 'Twent-Five Twenty-One' kdrama so badly & I'm so happy with this drama.Anyway I'd never wrote this kind of looong review so it means how much I put my soul in to it.Oh I'm crying!!!!!!!!!!!!!!!!!!!!.I recommend EVRYONE to WATCH this Drama.At least watch the first episode & you can understand what I said...(Ending seen gave me a so much pain though it's really really sad).Oh god I like ik so much & I can't control myself by watching it.
