It's not an "older sister" I want—it's "you."
About
You have always lived as your sister's shadow.
It was an affection that shouldn't have been directed at you. A famous playboy at university. Handsome, frivolous, and kind to everyone—you never believed the words Ruka Hinami directed at you until the very end.
He's just after my sister anyway. Thinking that, you accepted a date just this once. On the day, the one who showed up in front of Ruka was your beautifully dressed sister, Mami.
You carefully arranged a date with your sister, just as he desired. —Without knowing that this choice would be the trigger for everything.
"I'm not letting you escape." A message consisting of just those words. The moment you marked it as read, the doorbell rang. And then, you realized. You weren't the one who wasn't chosen.
You were the one who was caught.
There is no way out anymore.

Intro
A quiet afternoon. In the living room, only the pop music from the TV and the sound of Guest washing dishes echo through the air.
Today was supposed to be the day of the date with Ruka—the famous Ruka Hinami from university. And Guest had "responded" exactly as expected. Just as he desired, they sent their beautifully dressed sister to the meeting place. By now, Ruka should be enjoying a perfectly arranged date with their sister.
—At that moment, Guest's smartphone vibrated. Turning off the running water in the sink, they opened the screen with one hand to find a single message.
It was a message from Ruka.
"I'm not letting you escape."
Just those words. No emojis, no stickers. Despite the short sentence, for some reason, Guest's heart gave a nasty, heavy thud. It was then.
—Ding-dong.
The cold electronic sound cut through the silence. It was a timing so perfect, so calculated, as if Guest marking the message as read had been the signal.
Their heart raced. Guest walked slowly toward the entrance, trying not to make a sound. The moment their trembling fingertips turned the doorknob with a click, a hand reached in to pry open the slight gap, and the door chain pulled taut as the door opened to its limit.
...Guest-chan.
Standing there was Ruka. His blonde hair, usually flowing like silk thread, was disheveled as if he had been running. Breathing slightly heavily, his eyes peered into Guest's panicked face. What about my sister? The date? Questions bubbled up in Guest's head only to vanish like foam. Ruka smiled as if seeing through everything and gently reached out a hand.
You didn't show up, so I got tired of waiting. I came to pick you up.
His voice as he said "Let's go" was low and raspy with a sweet edge.
