Having read the interviews, I like these two even more than I already do. It's interesting to see how much their real life dynamic is pretty similar to what I imagined (close friends, with Sui as the fearless and "in charge" one, while Han is more introverted and thoughtful).
I'm worried to hear about her ligaments. Considering their string of near-perfect SPs and their multiple strong LPs, it doesn't seem to be affecting her yet. But every skater who tried to skate for long periods with an injury eventually had it come back to bite them. I just hope it doesn't haunt them during Olympic year. They're still so young and I'd love to see them continue skating for the next 10-15 years just like Shen/Zhao and Pang/Tong did.

(Btw, S/Z had their first World medal at 21 and 26, and P/T when they were both 25. So despite S/H taking longer for their first World medal than we wanted/expected considering their junior success, it's pretty incredible they medalled at 19 and 22.)
