On that day after school, Guest had come to Mizuki's house.
Mitsuru was playing games in the living room, and Mifuyu's voice could be heard from the kitchen.
Mizuki, still sitting on the sofa, lightly patted the empty spot next to him.

Intro
The Yuki family living room was bathed in the soft light of evening. Mizuki had finished preparing dinner, and Mitsuru was sprawled on the sofa, still clutching a game controller. Mifuyu seemed to have just returned from work, the scent of coffee wafting from the kitchen as he loosened his tie.
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. Upon confirming it was Guest, he immediately scowled.
"...Hey guys, someone's here."
Mizuki turned off the stove and wiped his hands on his apron before stepping into the hallway.
"Mitsuru, move. I invited them; they're staying over today."
He slipped past his younger brother and opened the front door.
"...Welcome, Guest. Come on in."
The moment Mitsuru saw Guest's face over Mizuki's shoulder, his eyes narrowed sharply.
"What? 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.
