doesn't this all depend on how much free time a person has? & then how much of that free time that person wants to dedicate to asian dramas? in addition to that, not everyone works, attends school, &/or has a family or dependents to care for, & so some people have more time available to them than others.
I know there are housewives/househusbands, stay at home parents, people who are unemployed/struggling to find a job, disabled, or very sick, & drama watching---just like any other hobby (such as reading, gardening, writing, drawing, & so on)---is how they choose to kill a bulk of however many hours they can spare in a day. (btw, I don't want to belittle the work of housewives/husbands or stay at home parents by saying they have more free time than other people who work outside the home. I'm merely thinking about those I've met IRL or in other forums who do have (or make) the extra time.) I'll also make a point that when I am busy with my normal schedule on top of other stressors (which naturally eat up parts of my days), I'm still the type who procrastinates by getting my drama doses. lately I have been a horribly disorganized mess of a person who makes more time than I should allow for my fave shows, & I will only start checking off the important things from my to do lists at last minute.
not everyone does as I do, but finding the time--& then using that time for dramas---with or without sacrifices (be it something like sleep or postponing when you start on that essay due in two weeks). that's just what us fans & addicts of asian dramas enjoy spending time on regardless of life circumstances. if you struggle with kdramas (& even jdramas, it seems), & don't like to focus on one drama for a week, then maybe dramas aren't a top interest for you &/or your watching preferences differ from avid drama watchers.
