When I was at school I used to watch only airing dramas, multiple of them. I DID sometimes forget what had happened the week before, especially if I'd happened to miss an episode.
Now that I have more free time I find myself just binge-watching stuff, which translates to starting a show and not moving on to another until I finish it (about 1 to 2 weeks max)
I typically have 10-20 dramas in my Currently Watching list, but I'm really just watching 1 or 2 lol. All the rest are dramas I've promised myself to get back up at, but still haven't.
