Updated with final thoughts.

What started as a unique concept became tiresome at times. Sometimes shows drag a few episodes but I've become tired at how slow this show has been moving. I've been watching it at 1.25x or 1.5x speed because the show is about to complete and it's dragging. It feels like there wasn't much of a story to begin with so what could have been completed in 10 episodes was stretched out to 16.

The earlier episodes of the show were enjoyable but you slowly start to get fed up and just wish the characters would tell each other what's going on. By the 14th episode, you are just waiting for things to be done already because you've lost hope in anything redeemable in the plot.

As far as acting goes, the male lead has only been able to express concern and sadness and the rest of the time he is straight-faced whereas the actress had to play a clueless bunny who weeps frequently. Not the actors fault for having to portray such characters.

Spoiler:
If they had established that the sister was dead and they just needed to find out what happened to her, I would feel less frustrated with this story. And the chef has not been able to open up his restaurant until the 15th episode which just adds to the madness. I had hoped that the ending might be able to redeem itself but alas, it continued to drag. One final question remains. Why? What was the motive? It is never explained. It seems like no one was interested in finding out if there were more possible victims. Everything else just seems like an attempt at rescuing this show but there's not much they could do at this point.

High expectations. Low return.

I am going to leave the final score at 6 but honestly I would not recommend nor rewatch this show.
