Does anyone know?

I rmemeber reading this comic a few years back. So there’s this girl and guy, i don’t remember if they’re dating/fiancés/lovers but they’re with one another for sure. The guy is a police officer i think? And one day he dies bc his car exploded. The girl then finds a phone and tried to call him, expecting it to go to voicemail, but it connects with him in the past. From then on i think she’s been talking to him??? And then I stopped reading cuz I wanted to wait until it’s completed but ended up forgetting instead ;;; Does anyone know the name for this comic please?? i’ve been searching all over and starting to think I’ve hallucinated it T_T
