It starts with a startling real fact in Japan:

"To this day, it is common—even after giving premature birth—that some moms do not hear “Congratulations.”

In the interviews with Preemie moms, they talk about their situations during delivery and their guilty feelings for having a premature baby. But as important: the fact that they never heard the word “Congratulations” from their loved ones.

In the separate interviews with the dads, they talk about their regrets of not being able to congratulate their wives at their delivery. After that, there is a surprise from Dads to Moms.

Picture books prepared by the dads to depict the story of why they and the people around them couldn’t say "Congratulations" and their feelings for their wives.

It is then that dads say the words that moms have long wanted to hear the most: "Congratulations.”
