It's not "another friend", it's the realization that that's on the start, and that Kusunoki is officially leaving him behind as her Debut succeeds and her arc starts resolving, and she doesn't need him anymore.
One of Keisuke's big points was that he has trouble with pretty girls (and girls in general), thanks to Hebikawa. He also was a huge Otaku and didn't really have much in the way of friends in general. I think that, if he realizes he's being left behind by Kusunoki and especially if he finds out she rejected him in her talk with Hebikawa, he might regress and self-isolate/sulk, which would put him square in Hebikawa's sights to start their shared arc together.
Not an attack, but you're not the first person I've heard call it "lazy", and I guess I'm just curious why because no one's actually expounded on that yet that I've seen.
The original reply didn't expound theirs so I also didn't explain mine. The part I'm calling "lazy" are what the most here wants. For the mc to just give up and go with the other girl (cause they like her more) who caused his trauma. Basically the fan service route is what I'm calling lazy.
Like I said previously, I'm fine whoever he ends up to. I don't have a solid ship here I'm just interested in the story and how it'll turn for both mc and fmc.
Just because you like someone doesn't mean they'll like you back, so what do you do? Either admire and move on from your feelings eventually, or make them like you back. The latter is what we usually read and are hooked to in romance stories. So when people bring the argument that fmc already declared she doesn't have feelings is dogshit. Of course she doesnt.
For the mc to just give up in a way is lazy
at this stage of the story. Like dude you just realized you like her and you didnt do anything yet, cant even ask her during the festival lol
If the author chooses your route and the mc realizes he is getting left behind, he doesn't have to give up immediately just because of that. Giving up is regressing to his past self. He is already friends with fmc, he just needs to focus more on himself then comes making her like him back.
If during his improvement he also eventually develop romantic feelings for the other girl because she was a key figure that helped him then sure might be a good story. But if he did just because fanservice? Because poor her, her parents are awful and he has to save her? Ugh
