Yobi, The Five-Tailed Fox

“Guem-ee makes Yobi promise to keep a conversation where he shared his favorite song a secret using this. Yobi later has Jong-ee promise to keep her being a fox a secret using the same gesture.”

Who is the shadow man trailing Yobi through the village, and why does he want a fox who has done nothing but cross the forest line to save a friend? That friend is one of the shipwrecked aliens she lives with, captured by a villager, and Yobi (Son Ye-jin) goes into the human world after him. Lee Sung-gang sends her to Geum-ee's school for maladjusted children, where she joins the students while a fox hunter closes in, and the longer she stays, the less safe she is.
