I can’t say much about it since my watching habits changed drastically over the past five and especially the past 2 years. I only watch one show at a time, that is fully subbed and finished airing. Only one time I broke this habit because of a special situation of a drama I anticipated with a certain actor, and he was switch so to be able to compare the portrayal of the ML’s character I watched it prior to being finish. That was the only exception so far.
So, if a drama was streamed later for whatever reason, I simply won’t notice that.
