Have you ever wondered if the person you like is dreaming about you? Teacher Yeoreum Han doesn’t have to guess -- she can make it happen, with her ability to walk into other people’s dreams. She can even link the dreams of two people together, and use this ability to play Cupid for her students. But her matchmaking goes awry when she enters the dream of Si-u Park -- a lucid dreamer, who realizes that Yeoreum is walking into his dream. Si-u and Yeoreum’s lives become intertwined after this incident, weaving a tangled web of love, friendship, and dreamers at Hanseo High. (Source: WEBTOONS)
