Who calls themselves a "real gay XX chromosomes"??? Are they trying to say they're a terf AND a racist and sinophobe?
...anyways, weird rants aside, this plot reminds me a lot of "Did Qi Fei take flight today". We have tall long haired girl who has unsupportive parents that hate basketball, although everything else is pretty different. I agree that the faces are a bit stiff, but I think they can still get the emotions across pretty well.
I'm curious about whether the parents will break with comic tradition and actually support their kid or if they'll have to do some fake tutoring sessions. I'm kinda thinking she would just benefit from real tutoring though with those grades though...
