Migi and Dali have been fully accepted as members of the Sonoyama family.
They behave just like real parent and child, but the twins notice that Mom and Dad are acting somewhat distant.
Suspecting that the Sonoyama couple might be hiding something, the two discreetly begin to search the house and stumble upon an unexpected secret of the couple.

Migi and Dali are shocked, wondering if they have been deceived. However, determined not to let things end this way, they execute a plan to retaliate against the Sonoyamas.
Knocking on my heart,
little fists, a work of art,
pummeling my shoulder.
.تدق على قلبي، قبضات صغيرة، عمل فني، تضرب كتفي
Kleine Hände – sie klopfen
meine Schultern und
berühren mein Herz.
Pequeños puños
golpeando mi pecho
Un buen masaje
Pequeños puños
golpeando mi pecho
Un buen masaje
Batte nel petto
piccoli pugni
un massaggio alle spalle
Pequenos punhos, acertam o coração,
batem nos ombros
