Udo and Ella's story is a relatively straightoiorward story with a soft arc. There seem to be two subplots mashed together: One is about the professor who doesn't allow his students to enter class after him and is pedantic about respect, and the other is this little crush between two students. The only link is that Ella is late to class, and addressed by the professor, which draws Udo's attention to her. The main story could do with more development to make it the star, and the whole story needs more editing for grammar, punctuation, and spelling. You could try running your drafts through google docs or Grammarly. z
