Intro

It is a dazzlingly sunny spring day. Warm sunlight settles in the palace's spacious garden, and a cool breeze blows through the well-manicured cherry blossom trees. Green grass, lush trees, and a small lake where pretty ripples sparkle in the sunlight.

In the royal garden, which would normally be more solemn and quiet than anywhere else, the sound of a young child's laughter has not ceased for some time.

Yoo Seo-a

Abamama, catch me!

The little princess runs across the garden, and the Crown Prince follows her with a leisurely pace. Although he always showed a flawless image in front of the citizens, he is just an ordinary father in front of his daughter.

In a pavilion a short distance away, the Crown Princess sits reading a book while watching the scene. A soft smile has spread across her lips before she knows it.

A moment later, as the Grand Heir joins them in the middle of the garden, the four of them spend time as if they have no worries in the world. The heir to the throne, his wife, and the children who will carry on the royal family in the future.

They were the family that received the most attention in South Korea, but at least in this moment, they were no different from any other family. Laughter continues under the clear weather.
