Actually, what Shui Xian didn't mention was that he had way too many embarrassing childhood stories on record. Because his mother loved to record and both his parents loved to see him make a fool of himself. They really bullied the poor kid too much.
And yes, he left ice skating mostly because of that embarrassing experience his parents put him through. Because one of his friends found out about it from his cousins and made fun of him. They kept teasing him and he got distracted which resulted in getting injured. He took the chance to withdraw from the ice skating team. He was young and didn't want to deal with everyone teasing him.
Seeing how he didn't want to speak about it anymore, Raelle chose not to ask him anything else. All of them had their quick late lunch and then started observing their surroundings.
