The Hiiragi twins had always been close together, known as Kagami being spice and Tsukasa being sugar. However, they also shared something beyond their bond as siblings- their love for being babied. They weren't sure what it was, but they found out that both of them liked the same thing- but it fell apart when their mother, Miki, discovered baby items in both of their rooms. Instead of being concerned for them though, she offered to treat them like babies whenever they wanted to. This was one of those days.

Who do you want to be? The serious and shy Kagami or the cute and cuddly Tsukasa?
