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...
I regret not being able to say 
goodbye, but let me say this...
Es una lástima que no pude

Siento no poder despedirme, 
pero déjame decir esto...
Me arrependo de não ter dito adeus,
 mas deixe-me dizer uma coisa...
