Since this drama is still in progress so I am not able to tell you what will come next so I can just help you to decide whether you should watch it or pass it. I am too patient to wait. once a drama completed then I start watching it but I accidentally start watching it. Not a bad choice though
Story:
As mentioned he ML got the superpowers and he used those powers to catch the criminals. Now a question arises why only the police department when he can use his powers in many other ways and this story is revolving around this question. maybe the beginning of the show somehow disturbs you but is you like REmember - then please bear with it for some time as this drama is of the same genre. it is not a typical romantic drama where ML aways try to protect FL. FL herself is a very strong person with the story ideology that she believed in. some parts of drama may disappoint you but most of the parts are well connected and well written. Twists are surprisingly well managed, unlike other thrillers. TBH I am not a Korean thriller fan but this story is a little better than others.
Acting:
Of course, we are aware of both the leads and both are amazing in your job. This is Yoo Seung genre how can he even skip a beat. on the other hand, I feel Yee see Young is getting matured and her acting is now improving. The rest of the cast is doing good and they kept you guessing who is the murderer with their mysterious expressions and there will be a point where you will suspect each character in each episode.
Music:
As it is a thriller so music is not as pleasing as I expected. I guess the only thriller I watched with amazing music is RONDO a Korean-Japanese collaboration ( if you have time must watch it).
Overall:
not so good as I expected not so bad as I thought if you have nothing particular to watch give it a try as Yoo Seung is truly eye candy.
