Kimi ni Koi wo Suru Nante, Arienai Hazu Datta

Yasutaka Iijima, a boy wearing glasses, sits in the corner of the classroom and wants nothing to do with Ema Kitaoka, a popular gal in the same class. However, after a chance meeting at the school camping trip, they started talking with each other, but only outside of school. They are both unsure of each other's "true feelings."
