ORESUKI Are you the only one who loves me?

Amatsuyu "Jouro" Kisaragi, a second-year high school student, has two dates over one weekend: Sakura "Cosmos" Akino, the student council president, on Saturday, and Aoi "Himawari" Hinata, his childhood friend, on Sunday. However, things take an unexpected turn as both girls confess their love for Taiyou "Sun-chan" Ooga, the baseball team's ace, instead of Jouro. Unaware of his friends' knowledge of his true personality, Jouro secretly plots to get Sun-chan to fall for either Cosmos or Himawari, with the other as his own prize.
