One day, Lien, who had been living an ordinary life after graduating from the academy, received a sudden piece of news. Dian, her childhood friend and the sole heir to the kingdom's ducal family, had contracted an unknown illness. To find a way to cure him, she sought an oracle from the Temple of Healing, but the oracle commanded, "For a fortnight, when the sun rises and sets, take a virgin's milk."

"Is this even possible? Can a virgin produce milk?"
"There's a magic potion that makes it possible if you take it."

Then, would Dian actually suckle from another woman's breast?
What... why does my chest feel so tight?

"They're looking for volunteers, but..."

"I'll do it. I, uh... what is it? I don't have experience with that."
