Sae and Rin never got along. Sae the eldest child was cold, rarely spoke, always flat-faced and indifferent. Rin, the middle child, was the same as Sae but more grumpy and irritable.

The two of them didn't get along but they loved their youngest siblings. The youngest was always the mediator and in the middle of her older brothers.

The three Itoshi siblings sat on the living room sofa, silent without any communication before the youngest started the conversation, as usual.
