>>87498252She seems to just have the most sincere personality and down-to-earth demeanor without being bitchy like Kronii, for example. She also seems to be genuinely passionate about music, songwriting, and drawing, and girls who have neat hobbies like that are cute. Even though I dislike Calli's music, I get the impression it's personal and meaningful for her. Whereas someone like Kiara seems to just enjoy music as a way to be the center of attention or be "famous". Also, if we learned anything from Calli's diary stream, she has had a lot of interest in nerdy hobbies since she was a middle schooler. It's not like she just picked up on a few things here or there, became a vtuber, and had to pretend she knows all about video games and anime. So we could share some genuine interest there. All this, plus she has a cute voice, big boobs, and, supposedly, a fat ass.
