Heartfelt exchange?

IDOS

Think of what a couple might say to each other during a wedding ceremony, but drop the first letter of each word.

This clue plays on the phrase "I do," which is what people say during wedding vows—a heartfelt exchange of promises. The answer "IDOS" takes that phrase and makes it plural, as if multiple couples are saying it at once. It’s a clever twist where the clue hints at marriage vows while the answer tweaks the wording slightly for the crossword’s needs.
