Shiganai Tensei Reijou wa Heion ni Kurashitai

Aria, once an ordinary high school girl, has been reincarnated as the daughter of a noble family. Hoping to enjoy a quiet and unremarkable life in her new world, she is instead thrust into an arranged marriage with Prince Eugene, a royal figure widely rumored to be eccentric. Her desire for peace is shattered when Eugene abruptly confesses his deepest secret: he is the reincarnation of the legendary warlord Oda Nobunaga. Aria quickly realizes that this startling revelation is the true reason the prince has struggled to find a willing bride. To her own surprise, Aria accepts his unbelievable claim without hesitation, a reaction that deeply intrigues Eugene. However, beneath her calm exterior, she harbors a desperate thought—she must conceal the fact that she, too, carries memories of a past life. Unaware of her hidden truth, the formidable prince begins to pursue her with unwavering intensity. Thus begins the passionate courtship led by a man whose strategic brilliance could conquer an entire kingdom, leaving Aria to navigate a romance far more turbulent than the peaceful life she originally envisioned.
