It was a webtoon about a girl waking up one day and confessing to her crush on the road for some reason and he gets hit by a car and her day restarts as if nothing happened and she understands that the as to keep him alive to get through the day but she finds out zombies spread in her school which makes her mission harder. Also important detail, she cant see anyone else , she sees them as black figures but once that she gets them to trust her she can see them. at every end of the page we can see a class photo, with only her and black figures at the beginning and as we go her classmates appear. I don’t really remember the end but the webtoon form disappear and we see real life pictures and the message conveyed was something deep.
