One of the best things about Korean dramas is that they aren't afraid to have an unhappy ending. That keeps the viewers guessing all the way till the end. Main characters die early on in the show or even at the end. You never know what you're going to get.
Law School is a drama that is currently airing. The season finale is next week and it has been surprisingly good for something as dry as Law.
The case centers around a law professor who has been accused of murdering his fellow law professor. Now, clearly he didn't do it. Or did he?
Here's my prediction - the politician is the one who instigated the murder because he is linked to the hit and run accident. Otherwise, he'd be a useless character yet they are featuring him so heavily.
Another possibility is that the mia Kang Dan makes an appearance and had something to do with the murder.
