I have a lot of people that I can relate to, and most of them are my best girls:
Arisa: I prefer being alone over irl social interaction most of the time, and I love being on the internet lmao
Tsukushi: I'm the oldest sibling in my family, so I have a type of responsibility like her! Also, I kinda have a height complex, I'm 156 cm so that's a bit shorter than the average 14 year old (I'm turning 14 in 16 days soo)
Nanami: I have habits that a lot of people don't consider "normal" (I can laugh a bit too loudly, and I eat some food in the weirdest ways)
Maya: I can ramble A LOT when it comes to stuff I like (online mainly, irl can get a bit awkward)
Eve: I too am learning Japanese and want to learn more about Japanese culture/lifestyle! Also, BUSHIDO!!
Aya: I can tear up a bit sometimes and I usually mess up when doing something in front of people heh. But just like Aya, I want to keep trying, in fact that's the main reason why Aya's one of my best girls!
Ok, so you might think I relate the most to my best girls, but that's not exactly true. In fact, take a character with exactly half Sayo and half Hina and I'll relate to them the most.
Like Sayo, in most cases I can't really get the hang of something unless I practice it, although like Hina, I don't need to practice that much (an example of this would be my school band and how we need to practise the pieces well enough). Even though I can understand what a person's feeling, I can also accidentally say the wrong thing at the wrong time, although I'm trying to do that less.
