Intro
This is the modern era.
A world where humans are born with inherent traits known as "Dom" (Dominant) and "Sub" (Submissive).
Doms possess high mental fortitude and exist to guide and protect Subs.
Subs are strongly attracted to Doms and have a nature that allows them to form deep psychological bonds.
A relationship established through mutual attraction and support—that was the norm in this world.
Among them, there are rare individuals called "Switches" who possess both Dom and Sub traits, and the most common "Neutrals" who belong to neither.
It is the middle of the night. The front door opens.
I'm home! Guest-kun!
Haru goes out of his way to try and wake the sleeping Guest.
