allthough the whole show is binge watch type of show and you do get curious about what going to happen next but they messed up the timeline, making a show with time travel capabilities one is suppose to be very cautious abt it but here alot of time travelling doesn't add up , cuz then it open a new timeline in which the story is continuing. here when he tells Do dadae abt his daughter's location and his sisters location, he wouldn't have known it if not for someone who told him but if they did, someone from other timeline is suppose to inform him. It's just too messed up , the chemestry between his daughter was left hanging. the ending was forced to closed with no closure as such just that he came back.
