After enduring years of abuse from his peers, Park Hyeong-seok moves to a different neighborhood to start a new life. Big changes are coming for him.

Hyeong-seok attends school in his new body by day and works a part-time job as his true self by night – only to learn that nothing has really changed.

Hyeong-seok takes his mother out to a cafe as his transformed self. Basco seethes with righteous indignation when he spots the two together.

Under Deok-hwa’s direction, Hyeong-seok unlocks his singing potential as their musical collaboration nurtures their blossoming friendship.

Competition heats up backstage on the day of the festival. Hyeong-seok and Deok-hwa leave their past and fears behind to deliver a song from the heart.
