After Being Reborn, Matsuda Found His Childhood Friend Had Become a Child

Jinpei closed his eyes, opened them, and went from being a detective to a baby who couldn't take care of himself. After finally getting his thoughts in order, he realized he had been reborn. He decided he would definitely give his idiot childhood friend a beating, so he'd understand not to make promises carelessly, even though Jinpei himself was the one who hadn't kept their promise. Wait, why hasn't his childhood friend of the same age been born yet? Why does the Hagiwara family only have one daughter now? Kenji closed his eyes, opened them, and went from being a bomb disposal officer to a baby who couldn't take care of himself. After finally getting his thoughts in order, he realized he had been reborn, and just as he was about to make his mark... Wait, why is his childhood friend of the same age already in elementary school? In this world, he's the only one who became a child. Growing up all over again gave them more things they wanted to do and more things they could do. For example, they could work hard to prevent their own and their friends' tragic fates. Meeting their former classmates made them realize that even more dangers lay ahead on the road to the future. If there was anything they could do, perhaps they could let their already lopsided skill trees branch out further and win people over with technology! As the timelines converged, every small change in the present would grow into new flesh and blood. So, come along and watch them grow up all over again. Tips: 1. The timeline of this story begins 29 years before Year Zero of the Conan timeline. 2. The original story's plot changes dramatically in this fic. 3. Contains many original background characters and events. 4. This is a lighthearted story told from a minor's perspective. The cases are in another crossover story, which the author is currently writing. 5. Some plot points are overly idealistic and unrealistic. Please don't take them as real life. 6. The inspiration for this story came from page 56 of the 2018 edition of Essential Grammar for the New Japanese-Language Proficiency Test N2: "Having a sister ten years older than me, I was looked after by her a lot when I was a child. Rather than a sister, she was more like a mother." 7. Chihaya is still like a big sister in this story. Those ten years haven't turned her into a mother. 8. I've seen every bit of support from my readers. I often open the page and grin to myself, and I treasure it all. I also read the comments and bookmarks often. Every little sign left by you lovely readers motivates me to keep writing. 9. This story was renamed on April 16, 2024. Its original title was My Childhood Friend, Eight Years Older Than Me. 10. The artist who drew the cover and character cards is the wonderful Gu Xiaogua, a domineering CEO! Guagua's art is gorgeous!

Wait, after saving his parents, can he still become friends with Rei?! It was an ordinary day when he got into a fight with someone over his looks. The fact that it was Christmas didn't change a thing. But meeting him on that snowy day made Rei Furuya believe that angels might really exist in this world.
