Aya is an A-list idol, daughter of an entertainment tycoon, and been working in front of the camera since infancy. Takuma is the eldest child from an absent single-parent household, with a younger brother to raise, and bills to keep on top of. The two from different worlds but both lacking a real childhood. When fate throws them together, they both make a desperate plea to the mysterious Wishing Tree and find themselves transformed into children again. Helping each other heal from old wounds.
