Wait..what!? (sanegiyuu)

so.. this was gonna be the og tea but I changed it and so basically it's very early like when Giyuu's still 18 but met tanjiro already, and Sanemi is 19(his older in my au:3333) and Giyuu basically accidentally slept with Sanemi and yk omegavese or mpreg and you'll understand it at the prologue Oh and Giyuu and Kokush...
