Kuroiwa Medaka ni Watashi no Kawaii ga Tsuujinai

There is not a single room that Mona Kawai enters where she does not become the center of attention—dealing with this everlasting spotlight is but a fact of her daily life. Mona's absolute confidence in her own charms, however, is shaken when she meets Medaka Kuroiwa, a recent transfer student to her highschool. Unlike all other classmates who constantly fawn over her, Medaka frowns every time they interact. Seeing his disinterest as something to be rectified, Mona pulls out all the stops in the hopes of winning Medaka over, only to be met with one stern face after another. Turns out, Medaka's indifference to Mona stems from his wish to one day become a monk, and hence must leave all worldly desires behind. As the unknowing Mona ramps up her attacks on Medaka, all her antics might lead her into falling for him instead.
