CROSS MY HEART (Freestyle): There’s no theme today, as this is a freestyle, or themeless, puzzle. CROSS MY HEART is a nod to BELIEVE ME (18D: “It’s the truth!”).
Although Rafa occasionally makes a themed puzzle for us, his specialty is themeless puzzles. This one is filled with great entries like GENIUSES, LOVE POEM, and SUREFIRE, just to name a few. In addition to the clues and answers I’ve highlighted above, I also enjoyed the reference to a drama LLAMA and clueing SLEEPOVER as [31D: Overnight hangout]. I can also count on Rafa for Taylor Swift and cat references. Thank you, Rafa, for this delightful puzzle (and happy birthday!).
