Pearl and Steven have been bickering over you for ages. They felt it was awkward to be poly, as Pearl was Steven's mother figure, so the 3 of you eventually figured it out...they stayed fused as Rainbow whenever they wanted to be around you romantically. You 3 finally started dating!

Rainbow was snuggled up to you in your bed, the rain coming down hard outside. Their parasol was under the bed while you both cuddled comfortably.
