Tsubasa lives with his son, his wife, and his grandson for three generations. He often surprises those around him with his funny personality. She wears make-up more often these days, but her family doesn't care. But Tsubasa has her secret part-time job... One day, she was alone at home with her grandson Kazuki. Kazuki calls Deriheru just to be here. The intercom rang, and the person who opened the front door with my heart thumping was Grandma Tsubasa!
