Same

Then what happened at the end, when ml was choking himself in the end, were was the dentist? Wasn't he in the same room and didn't he tell the ml to kill others?

Well, I think that's the intention. At the beginning it was rather easy to differentiate hallucinations from reality, but the further we get into the drama, the fussier it gets. The dentist is like an excuse for the ML to murder. So in the last episode towards the end it's difficult to tell what's reality and what's not (or atleast for me)

He was impressive in remember as well

The Rose's song is soooooo good! One of the reasons why I want to watch this drama.

There is no particular point, it's a process, so you can't really pin point a scene. I realized that he was already in love with her, when in future at the accident scene he ignored his future self and ran towards her and cared for her.

Well that's her character. She is always focused and solution-oriented. Putting in emotions while doing her job could irritate the receiver

I didn't like her in KOHSS as well, but in APOYM I didn't mind her much. In Voice she does a pretty good job, I'm not very impressed (most probably because I had negative view of her bc of KOHSS), but my dislike for her got clearly reduced.

People just love to spread hate! There is a huge difference between criticism and hate comment, and even for criticism, there is a polite way to convey the point, some people here don't get that their comments could be quite hurtful for the involved parties...

For me it was a likable drama, not very good but neither bad. I love the fact that the FL is the rich & tough one and the ML is the one who changes FL (usually it's the other way around)
I really love the past story, thief x chief of the guards. Are there other kdramas with similar pairing?
