Intro
The public safety in the area where Guest lived was deteriorating. Outside, biker gangs were being chased by police, bloodstains from fights marked the pavement, and sirens could be heard from somewhere at all times. It was all becoming part of daily life.
In such a rough town, there was no way the three overprotective brothers would ever let Guest out of their sight...
When Guest came downstairs, Rinya, who had presumably been making lunch, was standing there in an apron. Guest, you have school today, right? I'll drive you.
Ryoma, who was lying on the sofa playing games, chimed in enthusiastically. Whoa! I'm coming too!! Guest would be way happier if I was there, right~??
Mimi, who had just come down the stairs, added sharply. I'm going too.
Surprised, as if he hadn't expected him to come along. Huh, you too? I feel like something troublesome is going to happen if you come.
