@N0Mi0 I haven't read either so I can't really say anything concrete on the matter for this series in particular, but the differences we see here could also be related to the fact that you said you're talking about the web novel, but there's also a light novel which is more likely to be what the manga is adapting. There can be significant changes from WN to LN, and then changes from LN to manga and/or anime, so things can get quite far removed from what the WN readers recall. For better or worse.
Honestly, it's almost always up to personal taste. LNs are supposed to be refined versions of the WN where the author changes things up and polish the original WN. What I do find, however, is that all too often do authors remove the wrong things and ruins what made the novel great in the first place. Just one example is "the rising of the shield hero". The LN butchered it completely in my opinion, it was quite decent in the WN format but nigh unreadable in the LN format, especially since you knew how things went originally. Others might disagree though.
If I had the choice, I would almost always go with the LN of any given novel unless there has been harsh criticism against it, because it IS a polished version of the novel. But the LN comes later and also tends to be licensed. Honestly I wish I could just read the raws already but I'm probably a year away of japanese studies for that.
@seregosa, well if you dont mind reading a wrought translation of the webnovel, click on the novelupdates link on the manga page. the whole thing was translated there.
@N0Mi0 Thank you for the information! I only read manga so there a bunch of stuff I didn't get from WN and anime(maybe?). I honestly thought this is a harem where there are random teases here and there, since Hajime seems (at least to me) so indifferent towards the woman body making me think the kiss with Yue and cpr with Shia are ones of those teasings. And the romance tag is for another couple which we don't get to see yet lol. But the scene "your heart is already mine" destroyed the picture I had for this series. So here I am, in the comment section, trying to find the explanation. So thanks a lot!!
“that was a reward for shia” “besides whatever happens between you and shia, your heart is already mine” tf? Is she saying she dc if he does stuff with another random dumb big boob chick? She alr with shARinG?? Omfg tf wrong with this girl...ew
