This is so nice. It's amazing and is especially heart touching. Also it has a nice ending. About the OSTs..... OMG!!! They are really fabulous..... I haven't heard such nice sound tracks. Also all the background musics was really suitable for each situation. The background music which comes in the evil time is really creepy and scary. Really gets it's feeling. All the main role and supporting roles are amazing. Really I forgot it was a drama and I was like it was happening truly. I say to all those people who wants to see a kdrama.. It will really touch your hearts. 😍😍😍😍🤩😇😊☺
