The producers could have stopped with the first part. Disappointing and unsatisfactory ending. I wish that " I could just undo watching the 2nd part ". Last but not the least , the actors and their acting was above par . Liked the cast but ... It all was taken away by the final episode.. It's shit. Stop at episode 9 if you wanna stay happy.

Positives :
One of the things that makes Duty After School stand out is its exploration of the themes of survival and loss. The students in the show are forced to make difficult choices in order to survive, and they all experience a great deal of loss. This gives the show a sense of emotional weight that many other survival dramas lack..

Negatives :
The ending of "Duty After School" is the final nail in the coffin. It's so over-the-top and ridiculous that it's almost funny. The show tries to be both serious and campy, but it fails at both. It's a complete mess.

Overall, "Duty After School" is a disappointing show. It had the potential to be good, but it's ultimately a mess. The plot is convoluted, the characters are underdeveloped, and the ending is a disaster. I would not recommend this show to anyone.( Especially the 2nd part ) Just forget that a 2nd part exists. That would do good.
