The web novel is over, it's currently getting published as an LN.W8 so it's still ongoing and there is ending of novel?
Btw how many girls...? Just number is fine..
Oh and one more thing.. she already won (I rly like good harems without sad unnecessary drama) gyaru won for me already...
There are 3 girls, you can guess 2, the 3rd is the class president. They each get an ending, and some of the "events" give alternate routes for them. The WN is kind of written like a visual novel in that sense.
I will note, so far the pacing of the comic is a bit faster than the WN and it seems like they are kind of reducing the other girl's presence, so it might be that Yua is the focus for the comicalization.
