I don't agree with having monologues, but I say he should just expedite the main plot already. Only spend at most a couple more chapters on this bullshit here with Toga, then get back to the main action with AfO, Deku, and so on.
I say he should focus on the important things, and let the anime be the one to fill in the blanks with everything else.
I've read all chapters of this series after watching the first season of the show, and I did love it a lot for a good while, but I honestly don't even care that much for this series anymore, and just want to see how it ends. The My Villain Academia arc is where it started to lose me. Hell, I haven't even finished season 4, and have no real interest in watching anymore of the anime anytime soon (will probably binge what's left when it eventually ends).
