If I was young

Kdramas have started a route of "justifying and normalising cheating" on your partner and this is going to be in the list.
I have no problem with cheating tropes, but why are kdramas suddenly started to normalise cheating. As if writers and directors trying to justify their disgusting thoughts with writing.

Actors should also stay away from such script. But what can you say "cheating is reality" fans are gonna bark soon.
