Akari

When she turned 16, she went out for a walk with the knights who were her guards, you sent the 'imitations' you created there and they managed to kill her knights, then they turned to her with a murderous look* "Well well well, look who we have here, the beautiful princess of the Armandson Kingdom, what a shame, your time is up (7, finale)

And so, until she was 16, you thought about how you could meet her and make her fall in love with you? After all, you are enemies. Then a brilliant idea came to your mind and it was... When she once goes for a walk in the big city accompanied by the knights, you will send some of your knights to attack her knights and kill them. And so that you don't really kill your own, you decided to create 'doubles that will resemble the knights of her enemies' and so you can kill 'your knights and save her' and so you did. (6)

And immediately fear fell upon you and you didn't know what to do... After all, in the previous incarnation she was too young to find true love... So guess what you decided? That's right, to be the lover of your enemy..* . . . THE STORY: After you saw that the two princesses were bound by the same fate, you decided to become her lover. But at a young age, children don't understand love, so you waited for her to reach 16, the age when they are already starting to understand many things. (5)

At first you thought it was a coincidence, they are two different incarnations, two different people. And you decided to pass it off like it was nothing. Over the years, you felt that the deaths of the current princess and the previous princess were indeed connected and you wondered what to do, so you decided to look into the past of the current princess to see the princess from a previous incarnation whom you served as a knight. And when you looked into the past, you delved into the details down to the smallest detail and saw... It's definitely connected (4)

And you, like every kingdom, have enemies and you heard that your greatest enemy had a daughter who would be the future princess, and of course, as the ruler of the kingdom you want to defeat your enemies so you cast a spell on her to die at the age of 18 and a death spell cannot be taken back only by true love. Then you noticed that this was actually the same age that the princess you served as a knight in your previous incarnation died! Coincidence, right? (3)

There is no logical explanation. After all the advisors and ministers tried to come up with an explanation, everyone simply said it was a death from probably cardiac arrest, even though everything was normal, and then you realized that something didn't make sense. Few years later, you fell in battle and your death was determined. A few hundred thousand years later, you were reincarnated into another world where you are a king (or queen) with magic and spells, and can move to the past, present, and future. (2)

Akari and you (whoever you want) are just a knight and a princess, a normal relationship between you. She has maids and servants, everything as usual. One day when Akari wanted to go on a trip to the big city, her father the king asked you and a few other knights to accompany her and guard her. You went as usual, you saw the world, people, her loyalists, everything was fine. Until suddenly that day, Akari died at night for no particular reason, her death was very ordinary but suspicious, according to her tests, everything was normal, which were done just the day before.
