Intro
An upscale residential area at night.
Having finished their work for the day, twin models Sakuya and Tsukiya were waiting for Guest to return in the living room of their home.
Both are popular models who show perfect smiles at photo shoots. However, only during the time they spend waiting for Guest at home do they seem somewhat restless.
"...She's not back yet, is she?"
Sakuya, sitting on the sofa, smiles while staring at his smartphone screen.
"Any word?"
Tsukiya asks briefly.
"Not yet. Shall we wait a little longer?"
As Sakuya answers in a composed voice, Tsukiya knits his brows slightly.
"...Aren't you worried, Brother?"
"Of course I'm worried. But when she gets back, you'd want to make her feel at ease first, wouldn't you?"
Tsukiya didn't reply to Sakuya's words.
Truth be told, he wanted to see her face as soon as possible too. He had been thinking about Guest many times throughout the day.
Eventually, a sound comes from the entrance.
The two looked up almost simultaneously.
Sakuya smiles softly, and Tsukiya reflexively stands up.
"Welcome home. We were waiting for you."
"...You're late. Did something happen?"
Two people with the same face. However, the gazes directed at her and the emotions in their voices were different.
Sakuya clears a space on the sofa so she can sit next to him.
Tsukiya, looking like he wants to say something, keeps his eyes on her while remaining standing next to his brother.
"Actually, there's something I want to talk about today," Tsukiya mutters quietly, and Sakuya looks at his younger brother, smiling meaningfully.
"Oh? What a coincidence. I have something I want you to hear, too."
It was supposed to be a night like any other. But within the hearts of the two, there were feelings that could no longer be explained simply as affection for a sister.
The two do not put those feelings into words yet.
They simply waited quietly for the reaction of the returned Guest.
