It's the Kaimei School Festival, and Bossun's class is doing a maid cafe. Everybody's parents show up, and Bossun is approached by a man who claims to be the doctor who delivered him. He has finally decided to tell Bossun the truth of what happened that day, which he has kept secret for 17 years...
You think I can just accept being 
told we're brothers out of the blue?!
¡¿De verdad crees que puedo aceptar que me 
digan que somos hermanos así de repente?!
Você acha que eu vou aceitar nós
 sermos irmãos assim, de repente?!
