Okay im with you that the first episodes have alot od f stories and characters and you can feel that u are lost but because they are building each personality story and its role in the series and the story is build up on many parts and seasons because of that the senses are going very slowly but in each episode you will enjoy and will you be excited for the next one ! They have a good chemistry between the actors and they are doing their job in a really fantastic way ! I have watched more than 70 korean series and i swear this is from the best !
