Arata Shiunji

As the eldest son of the Shiunji family, Arata serves as the mediator among five sisters and one younger brother. Despite frequently being the target of his sisters' teasing, he remains a warm-hearted individual who places enormous value on family bonds. Upon discovering that none of his siblings share a blood relationship with him, this young man—who had always been awkward around women—finds himself torn between cherished familial ties and a forbidden affection, ultimately embarking on a journey of personal growth.
