'I'm going to get back at them. To the one who drove me away."
Reincarnated as a villainess from her favourite otome game in a previous life, Eliana meets Cecil, the prince who's a hidden character as well as her favourite.

When Eliana realises that it is Cecil who has interfered with her plans, she decides to get even.

As Cecil had planned, they live in the countryside as a temporary couple, but no matter how much he dotes on her, Eliana is still far from realising that she is in love...
