Dawon, a Santa Claus from the Korean branch, pays a large sum of money to have his own Rudolph and visits the Korean branch of Donor with a heavy heart. However, what Dawon found there was Korn, a fawn born without a leg. Korn, who was scheduled to be euthanized because he was born without a leg, is given an unexpected new life thanks to Dawon, as he is used as collateral until another deer is sold to him. However, Dawon treats Korn coldly, not to mention the zero possibility of Korn becoming his Rudolph since he can’t walk alone unless someone helps him, so he has no hope… This is the struggle of the three-legged deer, Korn, to become the Rudolph of Dawon.
