Yeonho Kang is a veterinary student with a strange ability: communicating with animals. Ironically kicked out of his residency program because of this, Yeonho is imposed to figure out how to get back on track, until he is offered a chance to work as a school nurse. There, he meets a strange and mysterious girl named Yeoul — a "feral child," unlike anyone he has ever seen before. A girl so different, yet in the most unexpected way, so similar.
