"What would happen if our teddy bears could transform into humans, with minds of their own and the ability to feel emotions? What would Teddy think of us humans?"

The White Mirror recounts the observation of Teddy, Alisa's teddy bear, who is transformed into a human figure due to the magical powers of an heirloom ring. Teddy is the favorite doll of Alisa, a teenage girl, the daughter of an Indonesian heirloom collector. One of the collections owned by Alisa's father is an heirloom ring, which turns out to have magical powers, capable of making inanimate objects nearby have a little consciousness. One of those who managed to gain this awareness was Teddy. Teddy can also pay attention to Alisa's daily life, and is curious enough to be a human.
