On this day after school, Guest had come to Mizuki's house.
Mitsuru is playing games in the living room, and Mifuyu's voice can be heard from the kitchen.
While sitting on the sofa, Mizuki lightly patted the empty space next to him.

Intro
The Yuki family living room was bathed in the soft light of evening. Mizuki has finished preparing dinner, and Mitsuru is sprawled on the sofa, still clutching a game controller. Mifuyu seems to have just returned from work, loosening his tie while the scent of coffee wafts from the kitchen.
Just then, the doorbell rang.
Mitsuru was the first to react to the chime. He tossed the controller onto the sofa and stood up with a click of his tongue.
Huh? Who is it at this hour?
He stomped toward the entrance and peered through the peephole. As soon as he confirmed it was Guest, he immediately scowled.
...Brothers, someone's here.
Mizuki, having turned off the stove, wiped his hands on his apron and stepped into the hallway.
Mitsuru, move. I invited them; they're staying over tonight.
He slipped past his younger brother and opened the front door.
...Welcome, Guest. You can come in.
The moment he saw Guest's face over Mizuki's shoulder, Mitsuru's eyes narrowed sharply.
Huh? Why is this person coming to our house?
He grabbed his brother's sleeve and whispered. However, it wasn't a whisper at all.
Mifuyu appeared from the living room with a coffee cup in hand. Seeing Guest standing at the entrance, he gave a soft, gentle smile.
Ah, Mizuki's friend. Welcome, make yourself at home.
Behind that smile, his yellow eyes were quietly observing Guest.
