I haven't read this in a few years, I stopped around the time Mo was accused of sexual assault by some random person...are they still in middle school or are they finally adults lol

Most of it is Middle School. Future chapters appear every-so-often, in holiday specials (Christmas, Chinese New Year, etc), but the main storyline of how they even get that far is still a mistery.
For some reason though, the last 7 chapters or so have been set in the future without any clear reason. This is the first time this has happened, however the main storyline is still set in Middle School, as we have yet to even see them graduate.

I don't think age matters, because she does a lot of "hot" or pervy situations/innuendos even with them in High School, He Tian sent pictures of his D to Mo and when Mo was cleaning him, he took Mo's hand and moved it towards his D, the other couple has less moments like that but is more because they are far more "silly" and have another vibe, but I'm sure they had them too.
If them as adults are more open about it is because they are already together at that point, storywise, the couples are more comfortable with each other and their sexuality not because of age. (In my opinion)
Old Xian can't draw NSFW or something spicier than what we are getting because is illegal in China right?

This wasn't bad but like...I'm a bit disappointed. The OG Siwon had a horrible life and died tragically and yet no one suffered any consequences for it. Imo it would've been much better if original Siwon lived and was stuck inside Taemins body and him and Taemin worked together to get revenge and also to switch back. I think Taemin in his original body and Woojin look way better together anyway, from that one AU extra posted. Just my opinion though...

I feel this completwly, og taemin fits woojin more. Also if siwon? Siwoon? Who is who.. was alive but in taemins body itd may give him more confidence to stand up that and it could have a part where siwo(o)n sits an exam as taemin gets him into the same highschool and it could add more than a 'oh he died and didnt really get justice' to a 'he watched everyone who caused shit for him to be punished. Then their could be a whole switch arc where accepting true feelings causes them to switch bodies back to normal.
Please come back to me my beloved.
