have the started dating yet? I keep coming back at random chapters and can't figure it out
Presumably, they have, but the exact point of the relationship upgrade was not shown, despite that being the thing most of us waited to see for years. That entire arc, with the first kiss and the broken-hearted fangrill, will in all likelihood never be continued. I might be wrong on that, but at this point I would not hold my breath waiting for it.
Whether the content the author had in mind is too explicit for Chinese authorities, or she just fell into an (understandable) creative slump over the censorship issue, is anyone's guess. Given the current climate in that part of the world, and the fact the author explicitly stated this has taken quite a toll on her, I honestly not only expect the work never to continue that particular arc, I fear we shall never get any romantic scenes beyond blushing, holding hands, and looking at each other longingly.
Because that is another thing I noticed. Their relationship was, presumably, changed to that of lovers. SJ was pursuing QT for ages (both in-universe, and in real life releases), and QT finally reciprocated, so it is a pretty safe assumption to make. However, we have not been shown any major change in their routine as of yet, and that is the thing, I do not think we will. The whole reason this work was being postponed from publishing was over the censorship of openly gay moments, like kissing and such. With the current Chinese censorship regulations, and the fact the author already ran into problems with it, the emotional slump she fell into afterwards... Honestly, I do not think we will ever receive anything more than these random "safe" little episodes from the lives of the main characters.
That in and of itself is not a bad thing, chapters are still cute, and humorous, or even serious and educational, like the last one, but before the whole censorship controversy blew up, this work had a little more substance to it, it was a slice-of-life that had several major arcs of deeper plot going as well. Now, it is just a random slice-of-life, and that is not the work I started reading, what? 4, 5 years ago? Too much time has passed for this to switch gears without a significant drop in interest, at least for me.
