Double-Aspect Paradox (смешанная)

Harry finds himself in a parallel universe travelling into the body of his counterpart, who happens to be the daughter of notorious gangster, James Potter. James is embroiled in a long-standing feud with rival mobster Tom Riddle, and in a bid to end the conflict, they agree that Harry and Tom will marry. This arrangement serves as a guarantee for peace between the two families.
Having spent years as a battle-hardened war commander in his own universe, Harry is now adjusting to the unfamiliar life of a young woman in 1954. He is indifferent towards Tom Riddle and views the prospect of marrying him as nothing more than a bizarre and amusing inconvenience. On the other hand, Tom Riddle is confused by the insane behaviour of his supposedly demure wife.
