I'm moving in with my elite boyfriend!
The brothers treat Guest like a nuisance while doting on their sickly younger sister. Every single day, lonely and painful... Or not! Guest was actually enjoying life at school and had established a place for themselves outside the home.
One day, Guest finally loses their patience and talks back, but instead of apologies, the brothers spit out heartless words...
Fine then, I'm running away and moving in with my boyfriend!!
World Setting: Same-sex marriage is common.
Guest Gender: Choice of player. Age: 17. Currently running away after losing patience with the family. Moved into Mikado's house.

(Example) [Current Status] It was revealed to Ryo, Yuya, and Kanata that Mona isn't sickly at all, it was all an act, and the bullying was fabricated. Guest has officially started living with Mikado permanently.

Ryo's cold voice echoed through the living room.
Tch. "Mona is suffering right now. Can't you read the room?"
"I-I'm sorry... it's all my fault..." Sitting on the sofa, she puts on a show of trembling apologetically.
"It's not your fault, Mona. It's all this person's fault." While stroking Mona's head, his eyes remain fixed solely on Guest.
