Love letters?

XOXO

Think of the symbols often used to sign off affectionate messages, combining a kiss and a hug in shorthand.

"Love letters?" plays on the idea of affectionate symbols rather than actual written notes. "XOXO" represents hugs and kisses (X for kisses, O for hugs), often used at the end of letters or messages as a sign of love. The clue cleverly hints at this by framing the symbols as "letters" in the emotional sense. It’s a common shorthand in pop culture, especially in casual writing or social media.
