Liliana, an arrogant succubus princess who disdains humanity, commits a minor transgression and finds herself imprisoned.

However, she remains unfazed. She is utterly convinced she can easily escape by seducing the man sent to guard her.

But the man was no ordinary man. No amount of seduction had any effect on him. Even when she allowed him to touch her or whispered sweet nothings, his expression remained unchanged. With eyes more lifeless than a doll’s, the man said:

“My name is Asbel Caan. I am the Valion Kingdom Knights' Third Division Commander, the knight ordered to monitor and guard you. And I am──impotent.”

The shocking truth was laid bare. Yet, unable to accept that her charms were ineffective against him, she desperately continued her attempts to seduce him. But somehow, before she realized it, she found herself developing special feelings for Asbel.

This is the story of how she goes from saying, “There’s no way *I* would fall for a mere human, right?” to wondering, “W-what is this feeling…?” to finally admitting, “I love you.” — and what happens after that.
