I really enjoyed the premise of the show, as the time travel aspect adds a lot of entertainment value and comedy when the characters were being thrown through time. However, I typically don't watch a lot of Asian dramas and I think the over-exaggerated reactions and sound effects were jarring and broke the immersion a lot. Also, there was a lot of potty humour (fart and poop jokes) which kind of missed the mark for me.

I was hooked for the first three episodes, but after a while I could tell that they were really trying to milk the misunderstandings portion of the show. Eventually it came to a point where I couldn't like the female lead's character anymore. For me, a lot of the to mains' interactions didn't seem very natural because of how much the female doctor would hyper-focus on negative aspects of the acupuncturist and ignore any time-travel hints (which is fine at the start but tends to get old pretty fast) for the purpose of taking control of the conversation. She also lost a lot of her doctorly-compassion for this guy by episode 5 which was really strange to me, considering he saved her life a couple of times and took care of her while she was in an unknown world. I think considering she got a taste of what it's like to be in a foreign land you don't understand, without anyone to rely on, it's extremely sad how quick she cast him aside when they got back (All because she saw him desperately trying to rescue his life's savings?). I know the scumbag/money-grubbing qualities of the male doctor character was pushed pretty hard at the start of the show but I think it made the writers lazy with the writing for the female character in that they thought viewers wouldn't find any fault in her actions, but, for me, any compassionate scenes she had were overturned by her dismissive actions.

I'm at the part where she stopped the guy from turning in his resume to the oriental medicine hospital director. Even though the scene was played for laughs, I thought it was really irritating how the lady surgeon wouldn't explain anything about the hospital feud or illegality of practicing medicine without a license, and just seemed to tell him to be content with going to jail, and that she didn't want anything to do with him. That lack of empathy and proper communication is so painful to watch.
