Apparently, I’m a Childhood Friend of a Saint in the World of Light Novels, and When We Meet Again After a Few Years at School, She’s Turned into Some Kind of Yandere?

One day, Alan, a mere commoner, met a girl who was being bullied by a few boys. The moment he saw her beautiful silver hair, memories of a world he didn’t recognize flowed into his mind. W-What kind of memory is this ……? He managed to fight off the bullies, and as he talked with the girl, he realized that this world was a world in a light novel, and that the girl in front of him was Charlotte, the saint heroine of the story. At the same time, he realized that he is a character who dies early in the story. He tries to escape as soon as possible, but Charlotte’s smile attracts him and they become friends, playing together every day. Five years later, Charlotte is adopted by a nobleman because she is a saint. Charlotte thought she would never see him again, but when they parted, they vowed to meet again at Nobilitas Academy, where the nobles and high-achieving commoners gather. Then, after overcoming the threat of death, he is reunited with Charlotte for the first time in a long time at the school! ……he was so happy about that but…… “I don’t want to be apart from you forever. Let’s be together forever.” “Who is that woman? Are you no longer satisfied with me if you are cheating on me? ……” Yes! Something’s very heavy! At first he was puzzled by the fact that Charlotte had become a yandere. But then he realized. Isn’t she still cute after all? Then anything is fine.
