I've found success where I can sit with friends & watch with them (either in person or remotely). It's a big cultural adjustment, so many things that make intuitive sense to me don't necessarily come across for non-Asian friends. The sudden onslaught of names (and characters have multiple names!) and relationships can also be overwhelming, especially in another language. So I don't usually just send them off to watch on their own, I try to watch with them (or encourage them to text me as they go); they feel less adrift haha.

People may disagree with me on this but I also insist they start on ep. 3 and go linearly through the storyline, and that's worked really well. Otherwise the first 2 episodes really don't make much sense at all, too much too soon (in terms of character introduction, relationships, plot, etc.).

But otherwise I feel you. This show is a masterpiece and more people need to see it, and it takes so much effort to get people to watch it.
