Tops sentencing has come in but not much information has been released. I'm not entirely sure how Korean law works, but it seems like he has a minimum 10 month sentence and a probation officer. If he goes against his probation officer /prosecutor, he'll get an additional 2 years.
Korea is super strict when it comes to drugs, but the western and Asian idea of dealing with things are different. in Asia, the simple fact that a person broke the law is enough for extreme punishment because it's a sign of bad morals and character. Korea acts like a mama bear. it's not just punishment; it's making sure you don't do it again.
However if you ask me, this is like pulling someone over for going 5 miles over the speed limit when someone is is going 20 over. it's overkill for sure. he's already been through so much, but of course the law doesn't care about that. I don't think this is honourable at all.
