Re Re Reincarnation

I still don't know why he keeps telling me he loves me. "I'm not interested in short-lived races," an elf woman tells a human boy. He continues to express his feelings to her as he grows older and older, eventually ending his life. However, a few years later, the boy begs God to reincarnate him, and he appears before her again. What is the reason he is so drawn to her? And what is his "secret"? A story of honest love between a long-lived elf and a short-lived boy, a hot topic on X (formerly Twitter), that transcends race and time, woven by the feelings of one boy. https://sai-zen-sen.jp/comics/twi4/re-re-reincarnation/
