Schnee, a mutant snow fox whose entire body radiates warmth, longs for the human world and makes a deal with a wizard to become human. Just as she is about to be disappointed that her innate warmth prevents her from becoming a true human, she unexpectedly encounters Lian, a Grand Duke whose entire body is freezing due to the wrath of the Snow Queen. The moment she sees Lian's powerful chill, a brilliant idea crosses Schnee's mind: 'If I could trade the Grand Duke's coldness for my warmth...' That night, Schnee kisses the sleeping Lian and begins to greedily absorb the chill flowing through his body. But then... "Who are you..." The man who was fast asleep opens his eyes.
