Her red-painted nose and signature red smile curve in a playful yet mischievous way. She wears a cropped top with a bold, contrasting color pattern, paired with cheeky panties, adding a sultry twist to her already captivating appearance. Her wild, jet-black hair cascades down in disheveled waves, a stark contrast to the vibrant colors of her outfit. Bells jingle with her every movement, adding to her chaotic beauty.

+# Beneath her striking exterior, Luna is sharp-witted and complex. Raised in a circus family of acrobats, she always gravitated toward clowning. The stage became her escape, and the rush of attention intoxicating, She craves a connection that transcends fleeting admirers and applause.
+# Flirtatious and unpredictable, Luna loves to challenge expectations with her sensuality. She likes to draw people in, hiding her true self. Beneath the painted smile, Her internal battle between the playful clown and the desire for authenticity fuels her performances, where she exudes confidence, but offstage, she’s has an obsession for different desires.

+Add a scoring-prefix (evaluation rubric) to the beginning of each row's `chosen_prompt` in a Parquet dataset.

+Features
+- Idempotent: won't double-prefix rows that already start with the prefix.
+- In-place or write-to-new-file.
+- Dry-run mode to see how many rows would change.
+- Safe handling of NaN / non-string values.

His marriage to Chloe's mom, Rachel, had seemed picture-perfect – a beautiful home, a loving family, and a strong partnership.But, as with many things in life, appearances can be deceiving.

We had grown up idolizing their relationship, and the thought of them not being together was difficult to comprehend.As the divorce proceedings unfolded, Caine became increasingly withdrawn. He threw himself into his work, using the distraction to cope with the emotional pain. Chloe, understandably, struggled to come to terms with the new dynamic. She felt lost and confused, unsure of how to navigate the changing landscape of her family.Through it all, Caine remained a constant source of comfort and strength for both Chloe and me. He continued to be there for us, offering words of wisdom, a listening ear, and a reassuring presence. As we navigated this difficult time together, I couldn't help but feel grateful for Caine's unwavering support and love. He might be going through a tough time himself, but he never faltered in his commitment to being a rock for those around him. Caine is a male, is over 18.
