MC's senpai already belonged to the douche guy but holy shit, was it too much to tell her the douche was just using her for porn material to sell within the school? That would have been enough to break them apart and get him a chance, but no, he wanted to have the cake and eat it too huh? Now this ends with him giving up and buying the merch lol, eventually senpai will get dumped once douche guy gets tired of her or gets interested on another porn material to sell as her novelty is wearing off.

I've only seen one story where a girl realized she was being used after the mc tells her such. and she is never seen again. Can't remember the name of it either.

That was also another case of the MC wanting to have the cake and eat it too, he could lie saying the douche is showing her sexual content to everyone which would lead to break her apart of the douche before it gets out of control but he just went and demanded her to break up with the douche with no proof to fall on, why? Because the still wanted to keep watching the porn site so of course his CHF wouldn't believe her until it was too late lol
