| Cross posted from Ao3 | What if Giyuu and Shinobu met as children? A moment of Serendipity, a lucky occurrence on the day before Tsutako Tomioka's wedding, has tied the lives of Tomioka Giyuu and Kocho Shinobu, as well as the people around them. As a child Giyuu was enthusiastic, a happy child who loves food just below as to how much he loves his sister, Tsutako. He was kind and open, and that attitude of his made him help out a small girl, crying and lost in an alleyway. Kocho Shinobu accidentally got lost while with her family moments ago, and she accepted Giyuu's help, or as she calls him, "Giyuu-nii" to find her parents. But along the way, she finds herself captivated to this strange boy's smiles, a feeling her young mind could not yet comprehend, but it made her heart warm and made her smile wider herself. But would these smiles last? _______________ Genre: Fluff, Romance, Angst. Disclaimer: I do not own Demon Slayer or any of its characters. All rights reserved to its creator, Koyoharu Gotouge.

Yet, as he takes his last breaths and finally finds solace in the life he's lived, he is mysteriously transported back a whole 8 years in the past. Now faced with a second opportunity to correct his mistakes and save the lives of those he felt indebted to, what would he do? -Certain character ages may be changed for the sake of the story (specific birthdays will be explained later). -Manga spoilers (why would anyone read a fanfic about the end of the series if they didn't finish the story)
