"It’s a story about a man and a woman who participated in a project to be frozen for 24 hours". Sounds interesting right? But what killed it for me already is the "only to be awakened 20 years later due to a mysterious scheme." I hated this part of the plot. I felt like the cast for the main leads would had a better relation with every character, had the cast remain as their younger counterpart. It was just too awkward having an old person acting young because they're technically the lead's younger siblings or younger co-workers. That just didn't work for me. I had to skip those scenes because it's too cringing for me. Don't get me wrong. I'm not bashing the older cast for their acting. I just think that it would've flow a bit better had it only been 5 years later. Then the cast would've remained the same and at least it would've been a bit more watchable.

But even if the cast remained as their younger counterpart, the plot wasn't all that great. We had this bad guy who wanted to destroy all evidence of this “Frozen Human Project,” just so he can keep his fake identity and get rid of his twin brother. He did everything from murdering his sister in-law & a professor that Professor Gap Soo was under & attempted murder of Professor Gap Soo and his assistant. He did all of that just to easily be arrested with still 4 episodes left. That made the rest of the drama pretty boring in my opinion. But how did the writer try to not make it boring? Keep one of the villain's goon still around, trying to hunt the main leads down which leads to a stabbing towards the end. What was the point of this? The evil dude is in jail so why would this goon still want to help out someone who has no power anymore? That doesn't make sense. What's worse is that there wasn't even a scene of his capture, just verbal words and a phone call about his capture. Talk about anti-climatic for the crime the goon did to Mi Ran. Because of this, we spent the last few episodes of pretty much everybody in sadness. This was a waste for the final week of airing.

Chemistry felt forced between the leads. I didn't see the connection. Because they both were stuck in a capsule, all of the sudden they like each other? Yeah right. I felt more sorry for Ha Young because she still loved him all this time and yet Dong Chan changes love because of being part of this project. He made her suffer for no reason. The love relationship between Mi Ran and Dong Chan isn't great either. A lot more bickering between each other from start to finish.

Others problems I had:
- It was never revealed who expose Mi Ran's participation in the frozen human project. We as the viewers had a guess who it was but the rest of the characters never dig deeper into this issue. Why did that random worker girl do it? We'll never know and we'll never see her get punish for it.
- This drama tries too hard to be funny. A lot of scenes that were suppose to be funny weren't funny at all.
- The writers trying to develop a second lead between Mi Ran and a student, who's suppose to be 20 years younger than her. Ew.

Ji Chang Wook is a great actor but this drama doesn't show any of his acting attributes which is a bummer. Won Jin Ah is an actress I will keep an eye on but again, I'm not sure if I would remember her role from this drama.

Overall, it's a different story situation, being handled pretty poorly. I say look for other dramas unless you really want to watch it because of the cast.
