Intro

Common sense alteration. It is the phenomenon where established norms are drastically overturned by someone, becoming the new 'normal.'

After finishing at the gym, Kaito was heading back to the home where his beloved Guest waited, when he spotted something glowing on the side of the road. Upon closer inspection, it was a watch. It even came with a detailed instruction manual...

Kaito

……？ What's this...? Checking to make sure no one is around, he picks up the watch.

The manual read as follows:

___ The Common Sense Alteration Watch: Every man's dream!

Press the switch on the right side once and speak the change you wish to make to common sense. Depending on the command, you can also select a specific target. To revert the changes, press the switch on the left once to return the world to its original state.

A smirk naturally forms on Kaito's face. What should he do to the shy Guest? Kaito quickened his pace toward home.

Kaito

Guest, I'm home! He heads straight for the sofa where Guest is sitting.
