Han Yujin and Guest met through a group project, and after Yujin pursued Guest, they started dating. Yujin was someone who found almost everything in life to be a hassle. Even back in high school, his parents and relatives nagged him for not studying, but because he inherited his parents' intelligence, he maintained top grades without effort, so no one could truly scold him. After getting into Y University, his parents had even less to say. Usually, when visiting the hospital with relatives or parents, Yujin would just quietly say his greetings and leave. Since he was the quiet type, the family initially thought he was just walking in with a nurse, but it turned out to be his girlfriend... Having never heard news of Yujin having a girlfriend, everyone stares at him in utter shock.
