Nope, his reaction to his ex was justified, sarcasm to his kouhai understandable, and the complete cold shoulder to the maid was a natural reaction caused by coincidentally and purely bad timing.

Just as I said, the only problem was that the kouhai dropped the act after the MC completely broke (timing issue), so she has to start over.

At least this girl gained her chance at earning back her favor, unlike the other two.

Yes, at least this girl turned honest and stopped the facade. The problem was, it was too late, thus she must START OVER, starting back from being friends first as the MC said.

This is something up to the author, not us.

Some are of the same world, just different jurisdiction and different mission - like the floors 11-20 which have the same boss.

Actually, you'd die if you didn't clear this floor due to the apocalypse (especially when its caused by not just one, but THREE constellations). That's how the tower system works.

Not just famous, but also SERIOUS, the author clearly wrote each arc well for one good solid reason - to emphasis the properties of the tower.

Remember - Lady Golden Flower could have lived happy if she weren't compared to Duchess Laviel (whom is not only competent, but extremely efficient to the point nobody dare refute). So the butler initally wished for Lady Golden Flower to regress back to the time she wasn't compared (by the people), but here's the problem - Lady Golden Flower is a pure b*tch as we have all known by now, she'll non-stop comparing herself to Laviel, bickering and nitpicking her pointlessly till the end, EVEN IF the people said nothing about it.

Given the point above, the "wish for Laviel to regress " is specifically the "wish for Laviel to regress back to the time she wasn't entirely capable" so that Lady Golden Flower can at least have some degree of equal footing against her. If you ask me, this "wish" is more like a CURSE and a MISTAKE. Its a curse because Laviel is a talented genius - the regression only did a pain to her status than her ability, and she can only numb to this torment endlessly unless someone breaks this binding chain of her (which she have prayed everyday before the constellations sent someone here); Its a mistake because the butler did not know or willingly ignored the ugly nature of Lady Golden Flower, and whole heartedly gave up everything of himself for her - which is a great misfortune for someone of this devotion, he did not deserve a master like that.

Remember, unlike Lady Flower, the butler's entire existence is no more. Body, soul and name (existence), all gone - that's the three offerings he gave. Lady Flower only gave her body for power, everything else that happened in this arc was due to the butler's wish.

And become the governor of that floor, fulfilled life with responsibilities and no longer mocked by the crown prince or king.

Well, subpar garbage is about right for this manga, just as it is for Martial Peak to be honest.

KazuTrash is right. Do you think God is fair? If you think so, I'm afraid to say you need a reality check.

Not to mention lack of logic, nonsense and unreasonable. I hope Professor Hongpeng f*cks him up physically to the point he'd blueball when meeting the MC next time.

We got an unreasonable professor with helplessness TAs last time, now a nice professor but with backstabbing, stupid and unreasonable TAs? Give our poor MC a goddamn break.

As long as we can spam Palspheres on them, yes. But there's nothing like that in this world...

With how powerful he will be in the future, especially after he killed off emcees with foresight ability, this much is nothing.

Exactly, there's no point to this duel, and no benefit to gain from it. But he can't leave unless he do so what choice does he have?

Preta. A constellation boss of the tower levels 11-20.

Now we know... Master Gu is a transmigrator AND reincarnator (he is already a Demon Lord's reincarnator before another soul was transmigrated to him).

Funny that this was pointed out since everything that Master Gu did to make it this far was either sweet talking, logic and reason, or b*tch slapping plot armor in the face countless times. Just these three and nothing else.
