From Lezhin: A study group is when students come together with the same goal and help each other succeed. But not all study groups are the same. And no one said that there should be some one goal. Sunggi is part of a training group that allegedly focuses on preparing for the public service exam. But that doesn't mean that's all they have to do, does it?
