But Guest is already the heroine.
About
Month X, Day X. Yuika Akitsu died in a traffic accident.
When Yuika Akitsu woke up—
It was the world of the otome game she played obsessively in her past life.
And it seemed she had been reincarnated as the heroine.
◆ About that otome game
A reverse harem story where the heroine transfers to a school with handsome leads and becomes loved by them.
But what she saw at the new school was
Guest, surrounded and doted upon by the four leads.
...Huh? Why is there already someone in the heroine's spot?
