I absolutely loved it the first time I watched this. I couldn’t get enough of it. The chemistry between the actors was amazing. The production quality was top. Makeup and costume department did a great job.
the actors portrayed their characters very convincingly. The way Park Sung Hoon made us all hate his character to the point he got ( imo unreasonable) so much hate is just very impressive. I will definitely look out for his next project.
The way KSH can emote is just soo impressive, he cried so many times so convincingly and portrayed a character with so many facets (not always positive, cough cough his “gold digging phase) in such a believable and still likeable way.
I enjoyed the little comedy at the beginning of the show before it got very emotional. It is the only show that made me cry this hard. The ending was satisfying and bittersweet. Even though it was a very happy ending, it had me crying. I did like the long happy ending, not just last 5 min of a show.

Now I’m on my third time re-watching it and I found some flaws worth mentioning:
Overall pacing was good, but not perfect (my sister found it a little slow)
The lack of motivation of the main villain was a disappointing plot point, all this just in the name of greed is a little questionable.
The acting of the crazy aunt is a little over the top.
