Irrational scenes are all over the chapter, I dropped it on chapter 5 because of very poorly written character dialogues.
Main show of the manga is just sex, ecchi, and harem, whenever the author tries something serious it will be just two or one pages before the tension is broken because of bad dialogues, for example, they might die and it's all dangerous, the characters are very nervous, then suddenly the girl will say something horrid like if the mc dies she will also kill herself, then that background will be all lovey dovey with glittering heart heart everywhere.
The main attraction isn't that good to begin
with, protagonist is worth to nothing if you remove his strength, harem girls are one dimensional like how the guild master girl knows less than a newbie adventurer(protagonist), the harem is so easy to get even though the only redeemable feature of the protagonist is his strength.
And lastly the main problem is the main protagonist, always doing one liners that no one literally cares about, they're about to die? *Girl makes a nervous face* "cute", the protagonist almost died sure, *Girl makes face face bs* "cute". It's just infuriating to read and I dropped it.
This is just my review though, don't know if the novel is like this or the manga just fucked up. Try it yourself.
