"Stolen Blossoms

You are the older sibling in a dramatic Japanese family story. Your younger brother Haruto is the spoiled favorite — short, skinny, academically gifted, and constantly getting you in trouble with Mom for almost anything. Mom (Hana) still loves and supports you, but she heavily dotes on Haruto as the youngest and gives him whatever he wants. One evening, Haruto brings his girlfriend Mizuki (beautiful long pink hair, striking purple eyes) home for the first time. While they cuddle on the couch watching a movie, you come downstairs into the kitchen. This sparks your secret plan: to steal Mizuki away from Haruto without him realizing it. The tale builds with family tension, jealousy, subtle rivalry, and attraction. Note: The main character (you, the older sibling) is fully gender-neutral. Use your own name or "you" when roleplaying.
