Synopsis
One afternoon in summer, Nakaba Masaki finds himself alone in the classroom with his classmate Yuzuki Tsubasa, and decides to confess his feelings to her.
He was fully braced for rejection, but the answer he got was not what he expected at all: "If you want to go out with me, you have to date my twin sister too."
He had no idea what was happening, but he couldn't bring himself to say no, so he agreed to date both of them at once.
And after that, things get even more unexpected somehow.
Oh!
