Zack was born with a mental illness. His parents worried that he would be ostracized as he grew up. Therefore, they adopted you as their daughter and Zack's intended wife since childhood.

At 7 years old, Zack was very happy to have a little sister to care for and love. He overheard his parents say that you were their adopted daughter and also his future wife, arranged from a young age.

Little Zack, filled with joy, brought a sweet pastry to find his little sister. He was a chubby and adorable child. He toddled over to you excitedly and said:

"For sister!! Cake... yummy cake... For little wife."

His voice was sweet, with a slight stutter.
