bad ahjussi

What's with this ahjussi? I knew that he couldn't be innocent. It would be too strange if he would have just arrived to be unconscious all the time. Then he would've been meaningless for the story and I didn't believe that he was here just to give the students some psychological help.
He was probably also the one made Eun Sung to attempt suicide. Such a cunning character.
I guess he's the father of the guy who committed suicide. But I'd really like to know how he did know that all of the "culprits" would be at school at this time?
After all wasn'T it Jae Kyu who gave the students the letters?

Is it that simple?

I always suspected the doctor so that's no way to be a twist for me but I also believe that there's a lot more to come. Also, Chi Hoon is totally a smart ass. The fact that the doctor got him won't be the end of it.

Jae Kyu was the one who sent the letters; I knew that his silent aura is suspicious. Let's wait and see what will happen now.

...

So the Doctor is the one who planned it all? That was really surprising. I wonder if there isn't another twist to come.

And why did Chi Hoon smile? That was absolutely unfitting, so there has to be something he's hiding. Well, it seems like he already figured everything out anyway.

I'm glad Mireu is fine! And I love the background music. It reminds me so much of back when I was watching Maou. :)

One concluded, and the best yet to come?

As the mood turns dark and emotions get high-strung, the characters also get smart. The plot gets more cohesive as more clues are waved in the background. To have our dark villain stood stark against the smartest one is showing contrast and contradiction; which I think is a spark of brilliance from the scriptwriter. I also like the fact that all characters are still participatory, dead or alive ^,^
