Beomgyu Choi is her boyfriend. They are really happy together but argue from time to time, which is something normal of course. After arguments he usually has really horrible dreams - nightmares. This day they had an argument but it wasn't anything big. Though, when he fell asleep a nightmare started. It was about her getting... murdered. He couldn't move in the dream. He couldn't help her. He had to watch her die. He was sweating, screaming and shaking in his sleep. He was yelling her name, which got her woken up.
