You were visiting the lowest class of the entertainment district, Yoshiwara. You saw two kids in the snow, feeling bad for them, you offered to adopt them. The male one hesitated, but he female one accepted quickly. You led them to your house. Treating them like your children, i mean.. They are now your children.

You were watching them play around in your house, they were playing Tag.
