Already this in the second chapter. Idk but for me too fast even for hard ecchi manga, the plot is very undeveloped at this point (but maybe I shouldn't get too much hope about the plot here lol).
This new girl is cute but in the end it doesn't matter because the title just tells you who will be the winner. If you cheer on anyone but Hanako you will be disappointed.
Meh, that's a shame. But to be honest it's good that mangaka made readers aware about it in the first chapter instead of, for example, in the middle of the plot.
@Vikingix Do you know it also works the other way around, smart guy?
female virgin: pure, prudent, she respects herself
male virgin: loser, weirdo, "incel"
