Some sexual references

Mostly mild

Infrequent to no violence

Some blood is shown

Fighting can be seen in some episodes, not too graphic.

English Sub:

F bombs and "S.O.B" are dropped more frequently than an average KD

Korean Dub:

Only a couple uses of the f word and more milder profanity "bitch, shit, asshole, damn, etc.)

Drinking and smoking is seen

Since the plot takes place in Itaewon, there are a lot of drinking, partying, and clubbing scenes.
