Man, vol. 24 already. I wonder if there are enough chapters to resolve;
1. Akira's long-lasting feud with Takeo (I sure hope this one ends with Takeo giving his blessing to Akira as the new professor, that would've been a satisfying conclusion to this plotpoint, at least to me anyway),
2. What Ryutaro, Takeo, and Shingo will do post-operation (I think Ryutaro will go back to NGO while suffering some kind of permanent injury in his hands from catching Shingo, Takeo will retire, and Shingo will work towards his dream which I highly suspect is veterinarian),
3. The professor electoral (we all know Akira's going to win just like how we all know Naruto will become Hokage, but maybe there's gonna be a conclusion more satisfying than Akira simply having more votes than the other two candidates),
4. What Akira will do after she's elected (for example what kind of structural changes will she do to Meishin's cardiothoracic department or if she will become basically Takeo2.0 but nicer),
5. What Kunitachi and Gunji will do after they lose the election (since Akira will win, then those two will lose, I still think that Kunitachi especially will drop out from the electoral to recover from this incident altogether and focus on Shingo's recovery),
6. What will happen with the Batista team as a whole (most likely the team is disbanded since Akira becomes the new professor, Arase is teaching young anesthesiologist, Fujiyoshi is teaching interns, and Ryutaro is leaving the hospital entirely to join NGO, I can't even think what Miki will do honestly but I sure hope that she becomes independent from Ryutaro and Gunji), and lastly,
7. Noboru's way of living as a doctor from now on, as cheesy as that sounds..
Would like to see other character's arc being resolved too, for example Kitou's response to Ryutaro leaving and what he will do from then on, there's also the matter of Kihara, but I really don't think we even have enough chapters left for everything other than the ones I listed.
