Taking care with sincerity gifts us the 'strength to live.' Author Kim Ji-an presents "Hydrangea Tea House," capturing the new daily lives of the field mice after "Tulip Hotel" and "Rose Mansion." The stories of these small animals, who diligently tend to their day, convey both the joy of working and the pleasure of resting, winning the hearts of many young readers. This tale begins when the field mice visit the hydrangea tea house run by an elderly toad couple. The grandfather tended the garden, and the grandmother made tea and snacks, but after the grandfather passed away, the hydrangea no longer blooms in the tea house garden. The field mice help the lonely grandmother by creating shade and generously watering the soil from early morning. They accompany her to the city to get new glasses for her dimming eyesight. The grandmother pours her heart into reading an old notebook left by her husband to make the blue hydrangeas bloom. As the sweat of the field mice and the grandmother gathers, the once-stopped day at the tea house begins to flow again. "Hydrangea Tea House" beautifully illustrates how the time spent caring for something with love can uplift the heart and restore the strength to live, all set against the refreshing backdrop of a summer garden. Just as small petals gather to form a lovely bouquet, hearts bloom brightly. At the center of the story is the hydrangea, which quietly endures through various seasons. The hydrangea must be pruned after its flowers fade and endure the harsh winter with its bare branches to bloom again the following summer. The color of the flowers, which changes from blue to red depending on the soil's properties, adds vibrancy to the garden. After a long wait, as the hydrangea bursts into bloom, the colors of summer finally fill the tea house garden, where the grandmother and the field mice have poured their efforts. Just like the hydrangea, which forms a beautiful bouquet from small petals, bright smiles spread across the faces of the guests who visit the tea house after a long time. In particular, the scene of a sudden summer rain showering the garden beautifully showcases the refreshing charm of "Hydrangea Tea House." The sight of the small animals opening colorful umbrellas and enjoying the sound of rain instantly cools the heat of the season and brings a refreshing vitality to the readers turning the pages. The scenes of hydrangea flowers, raindrops, and guests sharing tea together illustrate how precious time spent with loved ones brings delightful energy to life. A picture book that awakens the five senses on a summer day. Based on her personal experience of growing hydrangeas, Kim Ji-an captures the process of blooming in vibrant watercolor illustrations. Thanks to her careful observation of the hydrangeas up close, readers can feel the changes in the flowers, leaves, and branches. From the autumn garden, where the leaves turn red, to the snowy winter, and back to summer and spring, the four seasons unfold in beautiful colors, enhancing the visual pleasure. The rich descriptions of flavors that fill the tea house also enrich the joy of reading.
