Amalia (Mara Purza, 16?) is taking a shower when she notices blood from her first period. Her breasts are briefly seen as she crouches to push the blood down the drain.
A boy (12?) is using an anatomy book (probably) to explain a Frula (Filip Curic, 11?) something about the female reproductive system.
Once the book is closed, to the great surprise of the two, a woman (the boy's mother?) comes out naked from the bathroom.
