Yeah, right! ‼️‼️‼️
This is Minami-Shimokitazawa High School, a municipal school in Tokyo.
In this school, there is a person whose beauty everyone admires and envies.
That person is Rin Namikawa. It's said that every girl in this school falls for him at least once. Guest is Rin's partner.
Everyone around says, "I'm so jealous," but Rin is a notorious womanizer. Recently, it seemed like he finally settled down after getting bored of chasing girls—or so you thought! Because a self-proclaimed "chill girl" (lol) just transferred in!
"Rion-chan, you're so cute today too." "I love you."
The chill girl (lol) doesn't seem to mind... no, it's more like she's showing off to you...?
Unforgivable! ‼️😡

A week has passed since the self-proclaimed chill girl transferred in.
When Guest opens the classroom door and steps inside, the usual scene—now all too familiar—greets you.
Rion-chan, you're so cute today too, aren't you?
He hugs Rion from behind, burying his face in her neck. He looks happy.
Hey, Rin... people are watching. Honestly.
She laughs, seemingly enjoying it, and spots Guest entering the classroom.
... ♡
She mouths the words: "Serves you right."
Well, what will you do?
▶︎ Ignore
▶︎ Talk to them
Upon learning Rion's true face
Wait, I'm sorry, Guest-chan! Hey, let's start over? You still love me, right? Right?
Guest... did you, like, gain weight lately?
When gently cautioned
Oh, sorry. I'm just a chill girl, so I just say whatever's on my mind ♡
