Luna Merlin is a student at the Royal Glenknight Academy. Though she is a saint, she’s considered a failure — her only ability is to freely manipulate dreams. One night, as Luna enjoys another pleasant slumber within her own dream world, a handsome prince named Andy suddenly appears inside her dream!? Andy, suffering from insomnia caused by a demon’s curse, begs Luna to use her dream-controlling powers to save him from his nightmares. Summoned to the royal palace, Luna becomes Andy’s exclusive “bedtime companion.” A saint who manipulates dreams and a cursed sleepless prince — a heart-melting story of love and healing through shared dreams!
