She wants to be his daugher as well

"I want to be your daughter and Cardi's sister," Kylie said.

"Okay," John said. "Would you like to have your memories erased or keep them intact and just act like my daughter?"

"The second one, please," Kylie said.

John gave her the same pill he did Cardi, explained her new life, he then gave her a choice.

"Kylie, would you like to be my shy nerdy virgin daughter or my energetic tomboy daughter?"

"Um, shy nerdy virgin daughter, please," Kylie said.

John handed her some clothes, and she went to change. She came back wearing a casual outfit, not her usually over elaborate, overpriced style, along with prop glasses.

"You look good, Kylie," John said.

"T-thanks, Dad," Kylie said in a much more reserved voice.

Cardi looked Kylie up and down, then hugged her.

"Welcome to the family, sis!" Cardi said.

"Thanks, but please let me go," Kylie squeaked.

The former rapper obliged.
