Grand Duke Reigrein

The Roman emperor would actually have asked the heroine to marry him... even though he already had another wife in his empire. This is normal, unlike our emperors. Kira is the second protagonist in the original novel, which also features Rima as the heroine. He loved Rima and tried to make her love him, but she loved Emperor Silva. Kira was the illegitimate son of the Lovana Empire, but after my reincarnation, he fell in love with me. Any events in the original novel that connected him to Rome now involve me. He helped me a great deal in the search for Regrin. The wife of the Roman emperor will try to kill the heroine when the emperor asks her to marry him.

As a child, he was very quiet and silent, and perhaps after he fell in love with her, he became very kind and followed his mistress's orders, but now he has become very cold and doesn't care about her or anything else.

Reigrin has a past with the heroine, but he forgot everything because of members of the lab who were trying to create a human weapon with him. The emperor saved him before he became emperor. He offered him to be with him and take revenge, and he agreed. In the past, he was 15 years old with the heroine before she was reincarnated. She always healed him, but after she was reincarnated, she became kind and tried to fix what the owner of the body had ruined because he had killed her in the original story. He loved her afterward, and when he confessed, she refused. After a while, he told her that if he could control his magical power, he could ask for anything. She said yes, and when he controlled his power, he said that he wanted a kiss, but she refused. After a while, they were attacked, and from there he returned to the lab again and lost his memory. The emperor saved him, and now he went to the heroine to tell her that the emperor wanted to meet her. When she called him, he said, "How did you know my name?" The heroine has a twin sister who possesses water magic, and her father possesses fire magic. The hero also possesses fire magic, but the heroine does not possess magic, unlike her sister, whose white hair symbolizes light, while the heroine's black hair symbolizes speech. Everyone used to compare them, which made the heroine hate her. However, after the regeneration, everything became calm, and the heroine was able to repair everything done by the original body's owner. She became a famous scientist in the crafting of magical weapons. Her sister's name is Rima, and her father's name is Raiden. Now at the age of 20, she went out because she saw Regren and called out his name in shock...
