This has been on my PTW list for so long and it promises mystery with supernatural element and folklore stories with curses and ghosts... Say no more I'm sold.

Sadly this was so disappointing!
First, stories were so lame, nothing interesting or gripping about them, the mystery isn't really "mystering", each ep was tad too long than necessary in telling the whole story, it could be made a 30mins max per episode and you won't miss a thing.
2nd: acting was fine, nothing spectacular and the characters are barely fun to watch, they didn't even raise my curiosity about the lie-detecting mystery and the end proved my point, as it was the most anticlimactic end ever.

I don't really think its worth the rate, I don't even have anything on the positive side to say to sell it, it's just typical Japanese drama everything is so mediocre.
İt wasn't unwatchable, but maybe I had a little higher expectations than needed so probably keep your standards low and give it a go if you like this type of dramas.
