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...
At the time, I was convinced that

Naquela hora, eu estava convicto
 de que tinha feito a melhor escolha.
