Yes this is indeed a strange thing to see. The reason is the Korean coaches felt the existing partnership will not enable the doubles player to win in tournaments. So hence the constant changing in partnership which is not good at all for Olympic Games qualifications as the players already lose a lot of ranking points. Nevertheless through experimenting with different partnership glad that good partnership has been formed which can produce better results.
She surely has what it takes to win!! She def CM in SC the same way also def PVS in CWG but alas all these upcoming players will take a lil while longer to stay in the top form forever..
