Dear, See You at 9 O'clock

It started well, but why are there so few comments?

I accidentally saw the beginning and couldn't put it down. I spent the past few days watching it day and night, thinking about the protagonist all the time. It took me five days to finish it in one go, and it felt unreal even when I returned to the real world. The plot is exciting and compact, sweet and sadistic at the same time. I can't stop watching it at all. The only thing is that there are too many words that are reversed and confused, and I don't know why.
