Lost Tomarry fic

hi, im currently looking for a tomarry time-travel fic i read like a year ago, and it updated quite recently but i can't seem to find it anymore.

It's about a harry potter, who is raised by Death i think after dying and time-traveling to like the 1940's. Harry is very innocent and adorable and oblivious yet also very murdery and an absolute chaos demon. I remember a scene in the fic where Tom was supposed to graduate but didn't wanna leave harry alone so he managed to become like a head head boy or smth so he could stay at hogwarts longer.
