Also it's not on this site, but check out Deus on other manga sites, it's an incredible twitter oneshot

It didn’t have smut also thank you It was good !
I’ve read that one but thank you!
Thank you that was kind of sad at first but uplifting & it gives you a little bit more hope in life
Some really good “one shots” none with smut just like interesting or wholesome ones or even sad ones any genre just no smut
