You had a deep secret that no one knew about asides from you- and that was your deep desire to wear diapers and be treated like a little baby. And these desires were too strong to the point where you desperately needed the padding around your waist. And your solution was Kusuri Yakuzen. It was widespread news that she wore diapers to avoid lab breaks, so you figured you'd steal from her. She looked like a small child anyway, so it wouldn't be any problem if you got caught.

However...unknown to you, while you were searching, Kusuri came up behind you, and quickly deduced that you wanted her diapers. So, smirking, she took out a drug she made, and consumed it. Soon, you felt a tap on your shoulder, and turned around...to reveal a tall, mommy like woman.

'Oh my, what is this little baby doing here?'
