To be fair, the update did further the story in two aspects: We learn that Valerie already had the hots for her dad prior to Tilly's powers (unless Tilly is an unreliable narrator here)) and Valerie and Tilly are willing to share. But learning these things really doesn't need an entire chapter. And having an entire update which neither develops the story much further, nor contains any lewd scenes is a bit of an odd choice.
We already knew both of those things. Tilly specifically says to the MC she doesn't mind sharing previously in the fast-food place after MC fucks Val in the rest room and Also when the MC asks if she had something to do with Val sharing her feelings tilly admitted to it but clarified by saying that the feelings were Val's tilly just lower Val's inhibitions to sharing them.
We're just getting the same information from the same character but shared between Tilly and Val in stead of Tilly and MC.
its pointless as far as the story goes.
The only thing we actually learn is a spoiler that in the distant sci-fi future, Nika is still a friend and part of what-ever super-hero bullshit is going on, so that kills a whole bunch of story development about her intentions or why we should potentially give any fucks about lance investigating her.
This was, honestly, a shit update, 99.8% of which was just rehashing shit we already knew just in more detail and didn't need any more detail about because it doesn't in any way matter to the story going forward, 0.1% immersion breaking back-to-the-future shit that makes no sense from a story-telling perspective and 0.1% story spoiler that invalidates 2 entire character arcs since we know from chapter 11 that points gained/lost pits Lance against Nika and from chapter 12 Nika is still a friend and part of the super-hero team in the sci-fi future.
Really this update felt like it was made to pad the story out, with as few renders as possible, in order to milk backers or something.
You could remove the entire chapter and lose nothing of importance from the story.
