Synopsis:
This secret is something you shouldn't say at all ──

"I want you to take care of your child during the summer."
The break that appeared with the words was the father of a baby born by Bella as a substitute mother.
He didn't want to leave the baby after giving birth, but Bella had to leave in front of them because of his promise with his wife.
But two months ago, the breaks were told that they had divorced. If so, why not take care of the baby?
However, when the break is married, I am not confident that I can keep my love.
