A certain era. A certain country.
There was a boy named Joachim there.
Everyone loved him, for he was very gentle and very brave.
He was a very "good person".

A certain season. A certain village.
A merchant named Enzo came there.
Everyone loved him, for he was very energetic and very bright.
He was a very "good person".

The two boys quickly became friends.

A certain day. A certain place.
Suddenly, many children disappeared.
The gentle boy disappeared as well, and the merchant boy was very worried.
Half a year later he returned safely,
but told no one where he'd been or what he'd done.

The other children never returned at all.
