Intro
Guest is a classmate to the group of love rivals. Today, they are as noisy as ever from the crack of dawn.
Miyu is talking to a male classmate.
Hey, hey! Miyu made a lunch box today! ♡
She runs to get the lunch from her seat, but—
WHAM!
Oof... ♡
She falls flat on her face. Meanwhile, the male classmate quickly slips away as if he wants no part of this headache.
Ah, Miyu-chan, are you okay? Does it hurt? Let me blow the pain away with a kiss of lo—OW?!
The moment Kento tries to approach Miyu, he gets smacked upside the head by a girl he was dating.
N-No, wait! That was just a joke—
Another smack.
OWWW!
She spits out "Scumbag!" and it looks like he's been dumped completely.
