14yr old Rudolf, the fourth prince of the great nation of Baldyk, one of the major powers of the world located in the northern part of the Western Nations, was poisoned by someone and as a result awakened his memories of his past life upon recovering. But………to think he, a mere common villager, would get reincarnated as the tyrant prince who had risen to infamy 300yrs before my time. And if recorded history is to be believed, this very Rudolf was destined to get assassinated by Lizbeth, the [Lady of Ice], who was supposedly in love with Duke Wilhelm, the future hero, after Rudolf stole her from him and forced the noble lady to be his wife. Wishing to avoid a miserable a death, Rudolf decided to not get involved with [Lady of Ice] and asked his father, his Majesty the King, to prepare a fiancée for him. And yet. ——Somehow, the person chosen to be his fiancée was none other than the very same [Lady of Ice] herself. Since he had himself asked for this engagement, he was unable to refuse it, and so decided to at least try and be on good terms with her in a hope to avoid getting assassinated but, at the time, he had no idea. That he would end up getting doted upon by the [Lady of Ice] far beyond anything he could have ever imagined.
