What a year 2018 has been for kdrama, we had What's Wrong With Secretary Kim & 30 but 17 and now The Beauty Inside. TBI doesn't quite match up with the other 2, but it represents the same trend, doing away with tedious love triangles & instead using other tools to generate tension and I do love a good mystery... (even if everything is obvious about it on day2)

I felt that Lee Minky's acting was a bit off in this series, it was nowhere near as good, as it has been in This is my 1st Life. Still very decent ofc, just that he felt off here and there. I really liked the rest of the cast, especially Lee Dahee, she was really awesome here. Na Younghee is an "ajumma" actress I never liked before in any of the dramas I've seen her appearing in, but this time she was a good fit. The OST was fairly pleasant too, but not very memorable.

Now why am I not giving this 10/10? Well there are some issues. Probably this wasn't pre-produced, the way how they dealt with the rival actress's character was super strange, like the writers wanted to use her as a tool to mess everything up, but changed their minds half way. Episode 14, well this was really just a plain bad episode. I realize that they felt that a work labeled as "drama" needs to have drama in it, but oh man this was pretty badly executed in my opinion. For reference, Oh My Venus had an episode with the same writer intent, but it was SOO MUCH better in every way. Let's not even mention the time-skip part.. The assistant writers(interns?) responsible for product placements were definitely not very good, too obvious boys and girls..
There were some missed opportunities too. They could have done so much more with Segye's alter egos. I mean sure I liked it when she turned into a kid spending time with mom, but there could have been so much more. Remember how memorable Goblin's ghost stories were?

So yes, overall I was entertained, will watch it again someday. I hope that in 2019 we will have more dramas like this one.
