Zhou Zekai is a shy person. He doesn't actually enjoy receiving attention. In fact, excessive attention makes him feel even more shy.  This can be seen on multiple occasions during interviews, in which he barely speaks. His short and terse replies to questions make him difficult to interview.
Though he is not good at expressing his thoughts, his personality and flair in-game contradict this. When playing, he has an exceptional ability to excite the crowd.
