"A corporate executive who hates hobbies is trapped in an endless hobby hell at a cultural center!"

Dotori Cultural Center. A hot spot for middle-aged people, where they can learn and make friends. On Mondays, it is filled with the scent of ink from calligraphy, and on Saturdays, it is a peaceful place filled with the sounds of the grandmothers' funky town.

The story of a slightly odd group of grandmothers who end up defending the Dotori Cultural Center from the destruction brought by Goo Doo-ri, the vice president of Universe Group, and their humorous journey of growth.
