Kuroiwa Medaka ni Watashi no Kawaii ga Tsuujinai

From Kodansha:
Mona Kawai is the cutest girl in school, and she knows it. In fact, she has everyone wrapped around her pretty little finger everyone, that is, except Medaka Kuroiwa, a recent transfer student. Determined to win him over and solidify her reign as unchallenged queen bee, Mona rolls out the red carpet for her newest would-be subject, only for the stone-cold stoic to glare her down at every turn! Just how far will she go to prove her charms are truly irresistible and win over the last unclaimed heart in school? And why is it that her chest keeps getting tighter the harder he proves to conquer?
