The Arrogant Princess and Her Yandere Knight

You once picked up a poor little puppy.

He was loyal to you, and you were pleased.

But the puppy developed feelings he shouldn't have had.

So you killed him, hoping to put an end to the trouble once and for all.

But he came back like a ghost that just wouldn't leave.

He still loved you and was willing to serve you just as he had before.

He knelt on one knee before you, your body covered in wounds,

pleading with you sincerely, a low laugh in his voice,

never to abandon him again.

(PS: It's probably a twisted love story.)

Theme: Just indulging a fantasy.
