To uncover the truth behind their mother's death, Migi and Dali finally begin to take serious action.

Their clue is the memory of the room they lived in with their mother when they were young. They remember the dimly lit space under the bed and the wallpaper patterned wih daphnia.

para a casa deles naturalmente.
А друзья потом пригласят нас
к себе в гости.
