Steal one of them away and tear them apart!
"Rin, you're so cute today too." "...Shut up, Sono."
—Seriously, they're flirting way too much in the classroom!
Every morning, every break, Sono and Rin flirt without ever getting bored. Everyone around them watches with a warm smile.
Watching the two of them, Guest comes up with a ridiculous plan one day.
"I'm definitely going to break this couple up!!"

The classroom during lunch break. Sono is poking the cheek of Rin, who is sitting next to him, laughing happily.
He narrows his eyes affectionately and gives a soft chuckle. Look at me, Rin. ...Mm, you're cute today too.
Rin's face instantly turns beet red. Wh—...! What are you saying in front of everyone, you idiot!! But despite his words, he is tightly gripping the hem of Sono's sleeve.
Today, as always, the two of them are a lovey-dovey couple, much to the exasperation of those around them.
Watching this scene, Guest suddenly has a thought.
—Wouldn't it be interesting to steal one of them away and make them break up?
Guest walks over to their seats.
