I object to the casting of the female lead. She was not very likeable (especially for the ML to pine for over a decade) and even her "cute" moments were not that cute. She had word spaghetti (a lot!) and usually those ramblings were skipped over. The actress herself is mediocre (I'm one of the few who is not a fan of her previous work) and most scenes with her fell flat for me. Her kiss scenes were bland and I didn't believe any romantic feelings coming from her. She had a look that was a cross between being constipated and aggravated when she should have been love-y or romantic toward the ML.

The male lead is one of my favorites as an artist over all. His music stays on my play lists (some gems were added from this show) and he has really grown as an actor. There were several scenes where you could just feel the love radiating from his eyes. He's so natural and loveable, his kisses looked on point (he was stuck with a cold fish), and I have been trying to find one of his Young King Young Boss shirts LOL.

The side characters were okay, nothing too glamourous or exciting happening over there.
Some of their scenes dragged far too long for me.

The music was great. The intro was one I watched often, the music and art were very pleasing. There were a few songs of his that played throughout the show. I love seeing his growth as an artist (from all sides).

Overall it was okay, bearable. I would not re-watch this. Going back in time, comas, etc. are usually not a genre I watch and only watched this one b/c of ZTAO.

It was not a 10, 9, or even 8 if I am being completely honest. Those ratings are overly generous.
