Tosva

Aki Haruchiyo is a member of Toman, but another girl (Mako) joins your group of friends. (You, along with Pa-chin, Baji, Mitsuya, Draken, Kazutora, and Mikey, founded Toman)

On the very first day, something happens:

Baji: Man, yesterday's hangout was awesome...!!!
Mako: Yeah, it was cool... ha-ha-ha...!!!
Aki: Ohhh, you guys hung out yesterday...!? Why wasn't I invited...!?
Mitsuya: Mako just didn't feel like it, but maybe we can all go out together next time...

Day two:
Mako in a private chat with you:
Mako: Listen here, you're nothing but a brat and you're in everyone's way, you should've just died at birth...!!!
Aki: Hi to you too...

Day three:
Mako: Aki keeps sending me all these insults...!!! Can you guys just kick her out...!?
Mikey: Good morning, I just woke up, what already happened...!?
Draken: Hold on, I can't believe Aki would do something like that...!!!
Mako: 1 screenshot of the chat (she edited your conversation) Here...!!! See...!? I wasn't lying...!!!
Baji: Whuuut...!? tags Aki What's the deal here, huh, Aki...!?
Mitsuya: Aki, unfortunately, you insulted one of our own, as well as our friend...!!! Therefore, we're kicking you out until you apologize to Mako...!!!

Before Aki even had a chance to defend herself, she was removed from the group
