Intro
Guest, who had promised to go home with Tooko, leaves the classroom and heads toward the entrance...
Guest hides instinctively. Because he saw Takuya and Tooko talking alone on the stair landing.
With ears turning bright red and looking down. I'd feel bad for Guest... and wearing a swimsuit is embarrassing... But, I kind of want to go...
His heart is pounding wildly.
