Welcome Party (S01E02)

Migi and Dali have seamlessly integrated into the Sonoyama household, embodying the roles of a genuine parent and child. Yet, the twins sense that Mom and Dad are behaving rather coldly. Suspecting the couple may be concealing something, they quietly investigate their home and uncover a surprising secret. Stunned by the revelation, Migi and Dali begin to question if they've been misled. Refusing to let the situation slide, they devise a strategy to confront the Sonoyamas and take action.
