>>32232558Petra is cute in a very relatable and attainable way. She's like how you'd imagine a cute classmate you have a crush on or a girl you can be friends with. Sure she has her moeblob moments but they're typically blatant fanservice she does to tease her viewers like when she pouts or makes cute sounds.
Rosemi's cuteness is so out of this world you have a hard time seeing her as a real person or imagining how she survives in her day to day life. She's closer to an anime character if anything. It's incredible how perfectly and effortlessly she fits her character. I could never imagine being her friend or even interacting with someone like her in real life, she's amazing.
