You and I Are Polar Opposites

Suzuki has a desperate crush on Tani, a boy in her class, but she has no idea how to approach him. The two are on opposite ends of the class social hierarchy: she's loud and bubbly with lots of friends, and he keeps to himself, barely responding when she talks to him. But when she finally gets over her fears and admits her crush, it turns out that things aren't so hopeless after all.
