pro player group chat but it's a secret chat composed of all the people (a few of them star players, a lot of them second string or reserves) who look up to yu wenzhou, because at once point in their careers they did think they were good enough to make it. but none of them quit because if a player like yu wenzhou could find a way to carve out a place for himself, then why couldn't they do the same.
anyway the chat is mostly for encouraging each other and sharing stories. a lot of the players have DM'ed yu wenzhou at some point when they were feeling low, and yu wenzhou always had something encouraging or insightful to say. a lot of the advice gets shared to the group at large.
but the biggest group chat event is that every year around all-star weekend it descends into excitement and plan-making and a live "where's yu wenzhou right now" update so whoever is close can plan to ~randomly~ bump into him to say hello.
yu wenzhou doesn't know about the secret chat but sometimes he sees groups of pro players hanging out together and thinks it's nice that so many of the people he's had little heart-to-heart conversations with are all friends with each other.
