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 have heard from Akane-san generally 
about what happened the day you were born.
Tu madre te contó la historia 
de tu nacimiento, ¿cierto?
Has oído de Akane-san lo 
que pasó el día que naciste.
A Akane te contou por cima o que
 aconteceu no dia do seu nascimento.
