TLR - Scaredy girl is honestly what I felt on the inside during highschool but on the outside is just a lamb, who is also a bookworm, following the flock just because they don't want to be different, many year later they have then became a recluse.

Class president is confident and doesn't wear glasses. Much better than the walking trope the author is pairing her up with.
