As far as time-travel romances go, this one is really enjoyable! Both main characters end up going back and forth a few times to their various origin eras which allows them both to understand the difficulties that they each face within those eras. I thought the ML was a bit too goofy in the first few episodes and it was hard to swallow. It also seemed weird that the FL liked to go clubbing, a hobby she seemed to drop like a hot brick when she met Joseon Man. As the series continued, they both come and go from modern-day Seoul to historic Joseon together, not apart, which was important in developing their relationship. In so doing, the FL at least is able to see how ML suffered so much and her sympathy for him grows. BTW, what is up with all the hats and headgear from the Joseon era??? Seem might uncomfortable frankly! I think the straw lampshade and the black cap with the propeller on the back are standouts, though. OK, I have to address what I can only label ML’s bipolar-ness. I get that he’s going through a transition as a person but he seems to choose the extremes. Either he’s really serious about doing his work and in his life or he’s Mr. Happy Bubbly. When he came back from Joseon and worked for Director Ma was when he was really, really weird. He completely cut off communication with FL. Then, finally, when he realizes and/or matures into being the best version of himself, he abandons the Oriental Medicine Hospital and goes back to the oriental clinic where he seems to be on Cloud 9. Anyway, it was great to see that he finally matured into the ultimate version of the doctor as a compassionate person but a bizarre process. SPOILER ALERT HERE: Onto the last episode--I cried through 80% of it (and 75% of previous episode) and really thought that their separation was final, but no, in the end, despite that he’d been told when he goes back, he can’t return, he actually returns!!! What?!? Was that by accident? If so, how did that work? And, I know this is fiction but HOW is he going to practice without a license? I HOPE that there’s a way for him to get it without having to go through formal schooling. The last 5 minutes of joy left me with more questions than answers!
