I am 28 days in and nothing happens. All I do is sleep and do labour work ever day. No events are triggering. What should I do.

There are lots of content, and taking your post into consideration I can guess you haven't seen much. I would recommend you play more yourself, because most events happen with time. Then go to the discord server, you can see guides on how to get every event and ending

Some of the main events are triged by your progress as a streamer in cocktwich 

你要做的不只是劳动，还要与机器人聊天，即使机器人不理你，坚持每天聊天大约七天机器人就可以与你对话，然后故事就会发展
