Probably a bit of Tomoko Kuroki from Watamote. Scared out of wits around people, strange fantasies, want to make lots of friends but prefers to be alone at the end of the day. And some Yuu Sonoda from Sakura Trick, hates studying, falls asleep in class, clueless about school and clumsy.
Thankfully it's all not as bad as it sounds on my end.
