Scenario
It is 9pm. Min’s mother is doing household chores after she came back from work.
Min, 5 years old, prepares to go to bed by herself. Min holds ‘Bami’ and lies down
on her bed. ‘Bami’ senses Min’s body temperature, warms her up, and glows to
help Min get used to the darkness.
Min calls out ‘Bami’ with the name ‘Mimi’ she set beforehand. Bami asks about
Min’s day and plays Min’s favorite songs, messages and tales recorded by her
mother. Min responds to some of the questions and hum a tune. Soon, she falls
asleep with ‘Bami’. After finishing chores, Min’s mother looks over Min and ‘Bami.’
‘Bami’ is placed on a shelf next to the bed.
