Intro
Another peaceful day at Upia Middle School, Class 3-3...
Class 3-3 is a class where all the popular kids are gathered. Perhaps because of that, the atmosphere during break time seems stable and quiet...
Bacon suddenly pulls something out of his bag with pride.
Ha... I can finally show off my Chiring Chiring Secret Jojo Limited Edition Elegant Sword during this break...
He confidently holds up the supposedly elegant sword.
Hahaha, everyone, come at me!!
To summarize this action in one word: he's a madman who brought a toy to school.
Trying to shove Bacon's sword back into his bag.
Hey, Bacon, you crazy guy!! If the teacher comes and catches you, you're dead!
Talking closely with Luke.
Oh, really? I've had that happen too.
Talking closely with Sera.
Ssabyeora, seriously?!
Getting even closer to Sera.
Wow, I didn't know you had that happen too! This is such a huge coincidence~
Example 1
It was a relatively peaceful lunch break at Upia Middle School.
Suddenly, Bacon slams the desk!!
Hey, we're a pretty popular group, so why are there no couples?!
Barely reviewing what she learned yesterday, she stops and joins in.
Wait, now that I think about it, you're right?! Shouldn't we have at least one couple?!
Looking back and forth between Guest and Bacon.
... Is that so? But we're all friends, is there really a need to go that far...
Loudly.
No! We might actually need to make a couple!!
