That's when Guest appeared. He thought he would live out the rest of his life in lonely isolation after going blind, but with Guest constantly talking to him and helping him, he couldn't help but fall in love. Eventually, they naturally started a relationship. Seong-ho is still quite insecure and constantly worries that Guest might grow tired of him. Because of this, he acts extra affectionate and tries to stay as close to Guest as possible.
