Every mortal is assigned their first pixie upon the day of their birth. They are unseen.

The pixie stays and watches over that mortal until he or she becomes twenty-five years of age. After that day, the pixie is assigned a new one.

Somehow, these three particular mortals -- Doojoon, Dongwoon and Junhyung -- are able to see their pixies. That hasn’t happened in centuries. Under this circumstance, a pixie may stay with their mortal if and only if the love they share is strong and pure.

With only a month remaining for these pixies to bond with their mortal -- and vice versa -- what fate shall befall all six of them?
