Aria, a former high school student, reincarnated as a young lady of an unremarkable noble house.

She was roped into attending a marriage interview with Prince Eugene, who's rumored to be an oddball, and it’s during this meeting that he suddenly makes a ridiculous claim — that he was Oda Nobunaga in his past life!!

Well, that explains why the Prince still has yet to find a partner.

However, Aria calmly accepts Eugene’s tall tale, which inevitably piques his curiosity…

That won’t do! What if he finds out that I, too, have memories from my past life?!

Thus begins Aria’s days of being aggressively courted by the world’s most powerful prince who’s capable of unifying entire nations!
