The Tiger and Me

When Cheong-gyeong is stranded on Mount Baekdu in the cold, he's rescued by Baek Beom, the tiger spirit that rules over the mountain. It is only right for Cheong-gyeong's memories of the supernatural to be erased and he be sent back to the human world, but Baek Beom finds himself unable to let Cheong-gyeong go. They end up spending an entire season together before Baek Beom is forced to erase Cheong-gyeong's memories and let him return to his life amongst humanity. And thus their story ends...or it may just be the beginning, right when Cheong-gyung meets a mysteriously familiar figure amidst his ordinary life.
