This manhwa is an absolutely thrilling but grim story - would suggest you to binge read.

It's about people with supernatural powers related to time and dreams.
A shaman's daughter sees a horrifying prophetic dream of students dying in the school she teaches and a bunch of people along with her who witness the same thing. It's all on her, by finding them to prevent it from happening.

8.5/10
Plot - The pace is fast and the twists are really interesting as the story proceeds. It soon becomes a team effort by special people to stop a villain who makes this tragedy into reality.

8.5/10
Art - This might be a turn-off to people who have read stuff with gorgeous and detailed art since it provides a normal comic book art which isn't exactly appealing. Although it has added recurring panels that show events simultaneously to make us understand what's happening in the story.

10/10
Characters - Their development (only 1 chapter) gets overshadowed due to the story progressing rapidly but you quickly grow to know that they wish to change a sad fate which they always failed to do with planning, sacrifice, and efforts.

New ones are introduced and they play an important role in the story as well, given enough time to understand them before being dropped off.

I loved how it is all connected, keeps you on the edge and each one manages to pitch in their share despite knowing how futile it is.
Would recommend 10/10
