Interesting development but I'm still curious about a few things. Like MC's past (and hopefully he's the one who inspired the other 5 to livestream) or how Souta trying to expose Yuu would end.
The more chapters we get, the more I feel like the author does want a OTH(arem), as heavily shipped by @Tamerlane, even if the male relationships aren't explicitly suggested. It would be one of the few mangas where I feel it wouldn't feel unnatural for our cast of characters (as opposed to a fan service decision to add a new rival or trap character).
We don't know if he inspired them all to Livestream, but who cares right now because he already made everyone study together with his dense chadness.
Sorry guys but MC is really good.
I agree with the theory that he was the one that originally inspired them all to become live streamers. It would be good foreshadowing since they though showed how much of a positive force and inspiration he was as a streamer.
