"Wake up, Itsuki."
"...Hm? Okay."
As my mom gently shook me awake, I mumbled and curled up under the warm covers.
I wanted to sleep a little longer. After all, I had been physically active for the entire three-day weekend, and now my whole body ached with muscle pain.
Sure, my body in this life is young—or rather, still a child—so sleeping usually takes care of the fatigue. But the muscle soreness sticks around even more stubbornly.
"Nina-chan is already awake, you know."
"Uh!"
Hearing that, I quickly opened my eyes.
Oh, right. Nina-chan spent the night!
I scrambled out of bed, hurriedly changed my clothes, and headed to the bathroom to freshen up. When I finally made it to the living room, I saw Nina-chan sipping on some miso soup.
She looked over at me and said one word.
"Good morning, Itsuki."
"Uh, yeah. Good morning."
