Kentaro Hiyama attributes his success to his ability to plan out every aspect of his life — but then, something completely unexpected happens.

Morning sickness and other bodily changes start to affect Kentaro's work. He finally meets up with Aki and tells her about his pregnancy.

The ad campaign featuring Kentaro is a huge success, making him famous. With Miyaji, he launches an online community for pregnant men.

Aki goes home for her sister's wedding and ends up butting heads with her conservative father. On her way back to Tokyo, she gives Kentaro a call.

A figure from Kentaro's past comes back into his life, causing friction with Aki. She then finds out about a great job opportunity — in Singapore.

Aki makes a decision about the job in Singapore. Kentaro holds a press conference to apologize for the scandal caused by his father.

Kentaro goes into labor and is rushed to the hospital. Kentaro's parents and Aki wait together for the baby to be delivered.
