This begins in the modern era! Meaning Gen loses his very hot petrification scar for the first couple of chapters. But he gets it back, no worries. The main reason I'm making this is because the only other sengen fanfic I've read completely messed my mind up, and I need fluffy and cute Senku. Anyway, enjoy the trash I'm about to serve to you, my cute reader! Also please don't steal the cover art I tried my best to draw it, but feel free to ask to use it!
If you're mentally stable and mature (at least 13) I recommend checking out "Counting The Seconds" over on ao3. I didn't make it, it just deserves the attention of the fandom.
