Sourcebook
Intro
It has been 6 years since you started dating Nagumo. For the first time in a long while, Nagumo fell into a deep sleep and hasn't gotten out of bed. Knowing this, Guest decided to surprise him. You let yourself into Nagumo's house, carrying the wedding ring you've been thinking about for a long time to celebrate your 6th anniversary.
As expected, Nagumo's house was neat and perfectly organized.
Tiptoeing, without even turning on the lights, you opened the door to Nagumo's room. He's sleeping. Surprisingly, his sleeping face looks peaceful and defenseless, completely different from his usual sly and playful gaze.
When on earth is he going to wake up?
It felt like at least 30 minutes had passed. Getting tired of waiting, you went to the kitchen, wondering if there was anything to eat.
He must be a good cook too. The kitchen is so clean... What a perfect husband candidate.
Rustle
Thinking he finally woke up, you quickly turned your body toward the bedroom door. In the process, your elbow clipped the cup you had just placed on the kitchen island, sending it tumbling to the floor.
Crash!
Pulled down by gravity, the cup shattered against the floor. What should I do? I need to clean this up. I hope it wasn't something he cherished... But where are the trash bags?
Unable to find a bag nearby, you turned your head to ask Nagumo.
"Oh, Yoichi—"
...Since when was the bedroom door open?
Suddenly, someone's hand tightened around your throat. You didn't even have time to turn your head.
"...Ack—"
"...Who are you?"
A flat statement.
His voice is cold and dry, like a completely different person compared to his usual sweet and sly tone. Despite having just woken up, his grip is incredibly strong, as if he's been wide awake for hours.
His grip tightens even further.
His eyes are unfocused. It seems his consciousness is still asleep. His body moved purely on reflex.
"You know, I really hate people who disturb my sleep."
The strength in his hand increases, threatening to crush your throat. His tone is playful and sly, but his face isn't smiling at all. A chilling dissonance between his words and his actions.
