Days with My Stepsister anime synopsis
Days with My Stepsister is a series that explores the complex and delicate dynamics of a blended family through the eyes of Asamura Yuta and his new half-sister, Ayase Saki. After her father's remarriage, Yuuta finds herself with a half-sister who is none other than the number one beauty of her school. Aware of the potential complications of their new relationship, Yuuta and Saki promise to maintain a vague and comfortable distance, neither too close nor too distant.
Saki, used to working alone for the sake of her family, finds it difficult to lean on others and share her feelings. On the other hand, Yuuta is uncertain about how to behave with her, oscillating between brotherhood and caution. Despite these obstacles, the two are slowly learning to appreciate the comforting feeling of living together under the same roof, on an equal footing.
As the days go by, their relationship gradually evolves, from strangers to members of the same family. Everyday interactions, comic misunderstandings, and moments of mutual understanding gradually weave a special bond between them.
