Well in one of the chapters it said that he's been around Song Kai almost everyday for a month maybe some would agree that in real life that would be too soon to fall in love with someone especially when combined with confusion over your sexual orientation ... unless people mean that it's too soon in the story, that they wanted to see more chapters of Zou Xiao rejecting him and slowly fall in love with him, well that happened outside the chapters in that month lol unless there really are chapters missing
