I heard that Morosov has helped a lot in boosting Nob's confidence. According to a Morosov interview in a different issue of the same magazine I mentioned in the original post, Morosov says that Nob is sensitive and hard on himself by nature. Morosov scolds Miki a lot because he thinks that she is not hard on herself, which he thinks helps Miki's competition nerves, but that she needs motivation booster in practices to be harder on herself. But Nob is hard on himself, serious, and practices very hard. What Morosov thought Nob needed was to be open because Nob's mind was closed with the trauma of the DUI incident and he is also from a kind of good family in which mistakes may not be allowed. So Morosov says that he does not scold Nob and just says positive things.
I heard elsewhere Nob himself says that he is appreciative of Morosov's positive affirmation that helped his confidence.
Considering even Dai seemed so trusting and dependent on Morosov, I think it a good thing for Nob to have a coach with such a strong, competitive spirit who cares about him.
