What is a fate that even heaven can't stop?

Netizens reveal their marriage story:
On the first day, the power went out when they went to get the marriage license, and later that afternoon, the computer broke.
On the second day, their ID photo wasn't an inch, so they went out to retake it. When they returned, the appointment time had passed.
On the third day, heavy snow blocked the roads.
On the fourth day, they found a connection and obtained the marriage license.
Only later did they find out:
His father has late-stage liver cancer.
His mother has abnormal platelet counts.
They borrowed over 300,000 yuan for medical treatment.
The car he drives has also been mortgaged.
The only electric bike at home is still broken.
At the end of the year, his aunt bullied me.
He said: "Blood relatives only include one aunt, but a wife can be remarried!"
