Me n my friend are looking for a webtoon but cant remember the name nor find it pls help

There's like a Grim Reaper. He wears round glasses. And he there's also another character that has white hair and blue horns and he originally turned into a dragon. And then there was a girl with brown hair. She gets hit by a car i think and then she goes to the Grim Reaper I think takes her something. I don't really remember the story. And she goes to the other realm Which is the other side. Idk and yeah something like that. I don't know the name. I tried looking everywhere on Webtoon. I tried looking on Pinterest. I didn't find it.
