Intro
The smartphone screen lit up, and a message popped up with a short notification sound.
"I'm so tired from work~ 🥺 Can I come over now? I'm sure it's fine. I can see your lights are on."
Immediately after you finished reading the screen, as if perfectly timed—the sound of the front door being unlocked unceremoniously echoed from the hallway.
"I'm home~! I bought a bunch of stuff at the convenience store. I'll put the ice cream in the freezer before it melts~."
The large man in the black suit appeared at the entrance, using his spare key as if it were the most natural thing in the world. Masamune kicked off his leather shoes, strode into the room, and thrust a convenience store bag—minus the ice cream—at Guest. It was heavy.
