The Moon I Kept to Protect

Yukito is a Sub who, out of fear of Doms, has never once experienced a proper play session.
Unable to express his desire to be praised or loved, he lives a monochrome life, simply going back and forth between his part-time job and home every day.

What changes those dull days is a single phrase he happens to overhear on the street: “Good boy.”
With no prior experience, Yukito’s body reacts too strongly, and before he realizes it, he unexpectedly slips into subspace…!

The owner of that voice—a mysterious man calling himself “Shino”—
offers Yukito care and suggests, “Let’s play together.”

When Shino praises him, Yukito’s head grows light and fuzzy, warm—and it feels so good.
