Yeon-i, of whom not even a strand of hair could be found no matter how hard they looked, flew into Seol-woo's life bearing an unfamiliar name, scarred bare feet, and a battered appearance. “Can't you hide me for just a little while?” “What's your name?” “Kwon Da-mi.” Seol-woo tilted his head upon hearing a name that didn't suit her. Unanswerable questions filled his mind. And a moment later, “If I fall, if I fall asleep right now, can you tie me up…?” Unable to fight the overwhelming wave of sleep, her head drooped. “What in the world is this…?” Sun Woo-yeon, suffering from a severe sleep disorder due to an unexpected accident and driven to the abyss by demons. And Cha Seol-woo, the only person who can save her. “I can't live without you anymore. You mustn't abandon me and you have to love me for the rest of your life.” “I won't leave you. Everything I am belongs to Oppa.” That's right, from head to toe, without a single exception, she is entirely mine. *Medical information appearing in this work includes fictional elements.
