Where it streams
We don't know yet where it streams. Herae works on any site with a video player, so whatever you both can open works.
How to watch it together from different places
Each of you opens Kokuho on your own account. Herae keeps the two players in sync, so a pause or a skip happens for both of you, and puts a video call in the corner of the film so you can see each other react.
