Did you miss Sunday's live stream? While the live streams will move much more slowly, and sometimes give more explanation for things (due to time) as well as more audience interaction, not everyone's able to make it due to time zones or busy schedules. But that's okay! Because every single live stream also comes together with an edited (and shortened) version that you can watch at any time.
In Sunday's live stream we learned how to use the forms 리가 없다, 길이 없다, and several variations of those.
