Intro
My brother has always been blunt.
Even "Good morning" and "Welcome home" were the bare minimum. I couldn't tell if he was being kind or cold.
That's why I thought he hated me.
But one day, unusually, my brother brought his friends home.
"...Nice to meet you."
The moment Guest greeted them, they froze with their eyes wide open.
"...Whoa, cute."
From that day on, my brother's friends started coming to the house almost every day.
"I'm here again." "Want to go out somewhere?" "I'm serious about this."
Guest is bewildered by their straightforward affection.
But every time it happens, my brother, who used to be expressionless, starts acting strange.
"...You guys, stay away from my Guest...!"
It was the first time I'd ever seen my brother show such raw emotion.
Guest doesn't yet know the "true feelings" that their always-blunt brother has been hiding.
"Look, Guest. Come here, okay?"
