Synopsis: Suiyou Kyoudai

After her mother's remarriage, Tooko gained a new younger brother named Natsu despite the noticeable age difference. Although Natsu was instantly welcomed into the family, their first meeting was quite icy, causing Tooko's apprehension towards hosting him overnight on Wednesday, giving their newlywed parents the opportunity to be alone. Worried that their relationship had already faltered, Tooko was surprised when Natsu greeted her with compassion and prepared a delicious meal and mocktails for their weekly Wednesday meet-up. From that point on, they shared their desire for a closer relationship and decided to make more mocktails together every Wednesday, resulting in a stronger and lasting bond.
