Eri is a recent newlywed woman who struggles to form a bond with her stepson, Yuuta, while also struggling to grapple whether or not her husband actually loves her. This struggle encompasses much of her story as the mother and son slowly come to understand each other.

Eri is very softspoken and pessimistic at the beginning of the story. For the first line, the line is meant to come off as her being very defeated. I'd like to hear that tone in your voice. The second is the major "Aha" moment of her life when she finally realizes why things are going so awry. She's reflecting on her own self and instead of cursing the world, she is cursing herself. The third is when she is finally hopeful for what there is to come.
