Music recommendation: Perfect by Ed Sheeran.
The third point of view:
Reina and Niklaus were on an island he had purchased, sucking down on mojitos and laughing in the sun. The both of them had successfully escaped right after the wedding and came for a vacation in this private island Niklaus had purchased.
It turned out that Isabella had been joking about undoing the wedding, and it was the pregnancy hormone making her say things she didn't mean to. The kids had left for their honeymoon and they took that opportunity to take a break as well.
They had to admit, the triplets were a handful, and raising them was no joke. Niklaus and Reina needed a break and what other time to do it other than when they're all distracted.
Knowing their kids would follow them once they knew what they were up to, they arranged everything in secrecy and took them by surprise. By now, the kids must know about their disappearance since it was a day already.
