Oh lol. Well to invert everything I was just explaining, reasons some people prefer top Kim/bottom Harry...
- Harry is an "incredibly sensitive instrument", prone to melting down and becoming a fat blubbery mess anyway
- Womanising masculine guy getting railed and becoming a submissive bottom is a popular kink, gap moe
- Same goes for a small, mild guy being a secret top, contrasts and hidden sides are sexy
- People really like the idea of Kim helping an unaware Harry explore his own body and preferences (like he helps Harry recover his identity in-game)
Plus all the reasons a dominant Kim is hot either way.
