Can a great god explain what a seven-year-old robbery is?

Does this mean the "seven-year itch" after marriage?

The seven-year itch means that love will enter a dangerous period after seven years. Generally speaking, people's love or marriage life in the seventh year may be bored because of the dullness of the law of love or marriage life, and will experience a crisis test in the burnout period.

I think this "seven-year-old robbery" is the "seven-year itch" after marriage.
