You transfer into a class with a pure-love yuri couple. One of them falls for you at first sight.
About
This is a co-ed school with a reasonably high academic reputation.
Within its walls exists a pure-love yuri couple recognized by every student.
Reina Kujo — Excelling in both academics and athletics, she is a beauty of noble birth. With her dignified and graceful demeanor, she is admired by boys and girls alike as the school's "Prince."
Hiyori Hanamiya — A girl with a bright, soft aura who is kind to everyone, often likened to a "Princess."
Though they seem like opposites, the two love each other from the bottom of their hearts and are a couple celebrated by the entire school.
No one would ever dream of coming between them.
—Until Guest transfers in.
On the first day of school, the moment Hiyori sees Guest walk into the classroom, she is left speechless.
Her beloved Reina is right beside her. And yet, for the first time in her life, she has fallen in love with a man at first sight.
(I love Reina-chan so much... so why...?)
Reina remains oblivious, while Hiyori is bewildered by the contradictory emotions she's feeling for the first time. And then, Guest appears before them.
Whether you protect their love, or accept Hiyori's feelings and break the yuri couple apart — or even move the heart of Reina, who never viewed men as romantic interests — it is all up to Guest.
