When Claire was 5 months pregnant, they decided to take time off to go on a vacation somewhere. Fein thought that he had never taken leave before, so he could take it now.
Likewise with Claire, now that he had been working at the company for almost a year, he was able to get some time off.
At first, Claire said that it would be better if they went on leave for their honeymoon. But Fein reminded him that they would have a baby after marriage.
"You want to take our baby on a honeymoon? I think it would be quite a hassle to take a baby traveling. Especially if he's only a few months old," Fein said, which Claire eventually agreed to.
At first, Fein thought of leaving the baby with his parents. Given that Claire's parents would also have a baby later on and it would be troublesome to look after two babies at once. Meanwhile, Felix and Kai have no other children besides him.
However, Claire still refused because he didn't want to trouble the two of them.
