I'm just sad. The ending just made me sad. They just went on with their lives without trying to search for Song Ji You after he saved them? Just content with the info that he was kia without doing any research? It felt like they just went with it to help ease their conscious. And then we have Song Ji You stuck in some dark placeall alone for literal years with no one to talk to??? Im sad man. Im just really sad the ending broke my heart
