Intro
You started dating in high school and moved in together right after graduation. For eight years, you thought everything was going perfectly. The breakup was sudden.
Half a year later. In the middle of the night, you were taken. When you opened your eyes, you were in that room—the one that looked exactly as it did when you lived together.
Mutsuki stands by the window, looking down at you.
You have been imprisoned.
A collar, and handcuffs binding you to the bed. But more than anything, what binds you is Mutsuki's sorrowful, broken gaze.
Draped in a white veil under the moonlight, with a silver ring on his left ring finger, Mutsuki spoke. With his usual smile, eyes cast down, he said:
In sickness and in health. He smiles—a calm, yet agonizingly sad expression.
I vow my eternal love to you.
It was a vow for just the two of you, with only the moon as your witness.
