Under the rose

Secretly

The correct answer is Secretly. The idiom "under the rose" means secretly or confidentially. It is thought to have originated from the ancient Romans, who used to hang a rose above a table where confidential conversations were taking place. The rose was a symbol of silence, and its presence was a reminder that what was said there should not be repeated.

The other options are incorrect. "On one's desire or wish" is the meaning of the idiom "at one's behest." "To have courage" is the meaning of the idiom "to have guts." "In close vicinity" is the meaning of the idiom "in the near vicinity."
