MY LITTLE MONSTER (Tonari no Kaibutsu-kun), by Robico. First published in 2008 and first published in North America in 2014.
PLOT:
Shizuku Mizutani is a girl with a mission. She is determined to study her way towards a high-paying career and regards anything outside of that goal as a distraction. Her homeroom teacher bribes her with the promise of study guides if she will take some back assignments to Haru Yoshida, whom everyone believes is a terrible, violent monster of a boy who doesn't come to school. Haru falls for Shizuku almost immediately. Meanwhile, she's just annoyed that she has to deal with this weirdo and all the other weirdos he seems to attract. She just wants to study - she doesn't have time for things like "friendship" or "love"!
