[Bonus chapter] Zombie's day off [volume ???]

Once upon a time, in a different future or maybe some random past...

"Say, Zombie. Don't you think that we spend too much time together?"

The red-haired villainess, Cranberry put down her book and looked up at the blue-skinned corpse puppet whose lap she was using as a comfortable cooling chair.

"No."

Zombie's answer was instantaneous and definite.

"...ha... me neither actually... well, but you know, if we're with each other twenty-four hours a day, every day. Won't we eventually get tired of each other?"

The red-haired girl continued even after the initial response.

"Cranberry, you have literally told me something completely opposite many times already. What got into you all of a sudden?"

Zombie furrowed his brows and tilted his head in utter confusion, staring at the red-haired girl.

"...you must promise me that you won't laugh at me first..."

Cranberry suddenly blushed and looked away in embarrassment.
