This is my first review about any k-drama.I have seen many k-drama until now but I never gave review.The story was well written.The story had well connected from past to present. the acting of three actors was marvellous.They potrayed their roles falwlessly. They showcased love and friendship very well.While watching it you feel happy and during last few episodes your heart starting to ache.All moments were great when they were together on the screen.The music was also awesome.
