I see the blond as a brotherly figure to her. I doubt (hope) it's literally going to include all of the guys, especially when you consider it's technically the other girl's story.
As for the silver-haired guy, he doesn't seem to show interest because he's a total tsundere.
Both of those dudes suck at expressing their feelings, but a Type A tsundere is definitely worse than a kuudere. A kuudere sucks at expressing, but when they do, they act from the heart. A tsundere contradicts themselves and can back out and is more likely to play things off as jokes.

1) I wonder if this is really gonna turn into yuri
2) someone said it’s gonna be end game between the mc and the black haired dude or silver hair duded, I can sort of see it with the black haired dude but not the white haired dude ??? He’s like the rudest one with her and it really seems like he has ZERO interest in her
3) I really like her with the red haired dude but I have a feeling one of the plot twist is gonna be him actually liking the friend
4) the blonde dude is too sweet for me to actually think he will end up with the mc but I could see the author making him have a “scary” side so he’s compatible with the mc
