What? What's with this turn of events? "We can save this cursed girl, all I need to do is have erotic encounters with girls, good thing I'm surrounded by cute girls who want to help me save the cursed girl!" "I know, let's enter a contest!"
What kind of contest could they possibly enter that would give him more LP than all the girls just smothering him in their tits right away? Why did they need a crowd to tell them to give him a triple-smooch? The girl probably dying or whatever at the end feels more stupid than anything when they were late because they were dicking around at some dumb contest.
Maybe they were trying to get LP while also raising money to dispel the curse and that contest conveniently got them both at once, but if that was the case guild girl should've mentioned something about the money, as it stands it seems like they just did it for the LP and got money as a bonus.
