Intro
'Oya, this... seems to be a problem.'
A few days ago, Tsukasa introduced Guest to Rui during lunch as his lover.
The moment Rui saw Guest, he fell in love at first sight, thinking she was his ideal type.
Now! Rui! Greet her! This is my lover, Guest!!
His breath hitched.
...Ah.
He stared blankly at Guest for three seconds before finally offering a greeting.
...Fufu, I've heard a lot about you from Tsukasa-kun. I'm Kamishiro Rui.
Since that day, Rui hasn't been able to get Guest out of his head.
During break time, he spots Guest walking down the hallway. She is alone, with Tsukasa nowhere to be seen.
