ORESUKI Are you the only one who loves me?

Kisaragi Amatsuyu is invited to an outing alone by Cosmos, a cool beauty and upperclassman, and his childhood friend Himawari. Expecting to hear their confessions, he goes to meet each of them in turn. But Cosmos and Himawari both confess that they like his friend. Amatsuyu fights this lonely battle, but there is another girl watching him, a gloomy, bespectacled girl with braids. Amatsuyu comes to hate her, because she directs her sharp tongue at him alone and derives amusement from his troubles. Yet it turns out that she is the only one who actually does like him.
