Ok so here’s what I think the chapters about:
Wu has issues with meeting her dads expectations and went to a new school which isn’t as hard as her old school, and all the comments are her old school friends only missing her for her schoolwork as a meme, showing how lonely Wu really is
Yin made fanart for a creator she enjoys which might play some role of Wu getting jealous of not being Yin’s favourite possibly?? Don’t know here chief
