Weird

It started in a good way but then it all become a huge mess. At some point you believe there is some supernatural stuff but then it all gets partly explained in a weird way while other things are forgotten (why could hyunwoo touch jihye when he thought of killing himself? Who was the doctor? And the guy at the hospital who looked like jimin's friend?). I believe at some point the authors either rushed or changed the story and it's sad because the plot looked interesting.
