Suneo's Great-Grandmother

Suneo's paternal great-grandmother uses old wives' tales to impart values and good habits to Suneo. She is 93 years old.
She always says idioms to Suneo. She likes sweets.
By her appearance she looks like a really old woman. Also rather than the rest of her family, she is the only one who doesn't have a fox-faced shape.
