This drama had a great potential. It started quite interestingly. The idea is nice, but the execution was sadly poor, in my opinion.

What I liked:
- comedy
- youtube
- crazy first boyfriend
- kiss scene
- professor + brother Nam Tae

What I didn't like:
- second half of the drama
- not much focus on the frozen people
- plot holes
- crazy first boyfriend

I hated crazy first boyfriend at first but then I was enjoying his scenes thinking like "omg not him again hahahhahahahaa...." lol that was so stupid.
I liked how the lil' girl was telling about youtube all the time LOL
The drama starts off interestingly but the focus of it is the romance so it doesn't explore the frozen people concept which is quite sad.
The end was too predictable.
But overall it's a nice pass-time drama. Not bad and not good

P.S. this is just my opinion, you may really like this drama if you watch or you may hate it. So you can just try it out and see :)
