If we look at her entire work, Tan Jiu has quickly gone through every dramatic development aside from the basketball game, so to end Mo's arc as she did and now getting these vignettes isn't exactly out of the ordinary -- the sweet potato chapter and now this appear to be continuations directly after Mo stopped Sun Jing.
Except, she did not end the fangirl's arc. Not yet, the last scene is missing. It is not in the style of this story to have the fangirl confess (and even that was not actually shown), provide a short backstory on how she developed feelings for SJ, then just drop it there, SJ skips the meeting with QT, shows up another day, no questions asked (from us as readers).
She also did not return to the main story. They kissed, QT was quite reflective of that, and then... nothing, they behave the same as usual (in the sweet potato scene, as for this latest update, there is no way to tell how much time passed between the kiss scene and now, this is just a little snippet that could have happened months after they resolved everything).
Also, the story did not previously do what is doing now. The first kiss + the new (however short) drama was consistently built and hyped over a course of several consecutive releases, but the story has for the last 7 chapters been downright adamant at not going back to any of this. From a pacing standpoint, this sucks, and considering it coincided with the whole censorship issue, it really might be down to the author not being in the mood to tackle it.
So, Tan Jiu could have just taken an extended break from the main events to recharge and to think about how to continue.
Exactly, and if she really did that, it would have been better, in my opinion, to take a break from new releases and just think things through. This will sound callous (or shameful, if that feels better for you), but I am not invested in this story because of the author, or what she is facing in China (as appalling as the situation is there). I am invested in the story itself, and when pacing starts to go all over the place, as it is now, I am not really interested in exactly what real life circumstances in author's life led to this. However deplorable the censorship issue is, it will not suddenly make me think "nah, pacing is completely fine, the author is just going through some rough patches in real life".
Many people were displeased with the fangirl getting in the way of the post-kiss aftermath. Now, we are getting neither the aforementioned aftermath, nor are we getting the fangirl arc conclusion (which is something I got invested into as well). Personally, I find this to be lacking. Not heavily, since the updates themselves are still cute, but my overall enjoyment of these episodes has been lower than it would have been had they been released later.
