TL;DR. Best reward is WITH the LoRA at 50% (0.616 vs 0.488 for BASE). Note the infatuation target dimension stays essentially zero in every condition (emo ~0.01 — the model cannot score direct infatuation), so the reward win comes entirely from richer vocal-burst blend (0.453 to 0.540), higher genuineness (0.110 to 0.150) and lower WER (0.269 to 0.198), not from any measured emotion. The LoRA colors delivery toward a sexual-lust/longing register (corr Sexual Lust 0.81, Longing 0.51). The trade-off is a quality dip (0.625 to 0.515); higher merges (100/150%) keep the blend but add no emotion and lose reward.
Without a LoRA
Best: neutral prompt, no LoRA → reward 0.49
GENERAL: A voice to the extreme expressing infatuation, a dreamy, smitten voice, lovestruck and breathless with infatuation, impossible to hide.
