Here's a very good story of using girls as a plot device, but with characters that are neither dismissive nor disrespectful of them: http://www.mangago.zone/read-manga/gunjou_no_subete/
Idk why you got those dislikes when what you're saying is true imo,i really hate how he dismissed girls
Second story was misogynistic. I was waiting for the protag to properly apologize to the girl, but it was brushed aside for the angst. It sends a bad message to portray girls' feelings as fleeting while the feelings the boys had for each other as the true one (feelings are feelings; your feelings aren't automatically more valid just because it's towards the same gender). You see this a lot in BL but it's especially bad here when the protag is super vocal about it (in his head, which makes it worse, because it suggests that's his true belief).
These stories are not for me. I did like the after story with Hibi. Had their character and dynamic been like that from the start, I'd've enjoyed it. Both the stories were gentle and emotional, something I'd usually like, but it was just a tad bit too sentimental with little substance (huh, kinda reminds me of how Takarai Rihito sets up her stories).
