A few things to ask from this: 1. Did Teio get a different trainer? 2. Did Rudolf confess to her trainer? 3. Was she rejected?
Looks like Teio is now grown up and dad is visiting her. I am curious if Rudolf and her trainer actually got together. but you're on to something. That does look like Teio has a new trainer
Rudolf (Imaginary): Look at you! You've become a great student council president, Teio!
Teio: My plan to get the president to praise me~!!
Rudolf: I don't really get it but sorry
also I'm no longer the president
Today I'm at the academy for an observation work. I've been watching your performance from afar. Teio is a truly splendid student council president who is worthy of leading everyone.
Teio: President...!
Rudolf: Knowing some part of you doesn't change make me feel relieved
