Binge watching, it's my thing, I seldom live watch, the air for episodes in a week kills me.
For Korean dramas, with usually 16 episode. I'd be in my pajamas like a couch potato in 1 weekend. So yup 2 days is a usual pace.
For Japanese dramas, with their shorter episode count and shorter duration, 10 - 12 hours is all I need.
For Chinese dramas, since their episode count is waaaayyyyy longer, I tend to get 6 to 8 days. Though it depends on how good the drama is. There has been a time when I watch a 70 episode drama in just 3 days, i fast forwarded 75% of the time since the filler scenes was just soooo much. But the awesome ones like Nirvana in Fire, The Untamed, Story of Yanxi Palace, Story of Minglan, and etc.... Man it took me forever. Even rewinding a couple of scenes that is related to some conspiracy theories. And some things I might have missed out when I first saw it, and just realized it's significant as the crisis and plot thickens. But no complains to my time binging them, each hour was worth it.
