she actually doesn't deny anything, no one in the main ensemble has outright professed their feelings of love to her. Its also established that she's unsociable since her past life so her common sense is a little messed up. Its also revealed early on that because of her unsociable personality its ingrained to her that she's unlikeable (check early chapters where she first met raid and the fact that she avoided her classmates because she thinks they hate her) and thus wouldn't even think of the possibility that people romantically like her, and it tracks because as far as she knows, they're all just friends and to be fair, they do act like that in front of her. Mystia is also someone that thinks being buried with Melo in her death is #normalplatonicfriend stuff so that should show you that to her, the things the guys have been doing are NOTHING
Her will to deny other people's feelings because they don't fit HER version of them is pissing me off (I stopped at chapter 13). She's not treating them like real people she can touch. "but in the game,.
. game,... game"
Girl, if you're so worried about the events in the game going like the game, then you need to act like the villain like in the game. She keeps ignoring the fact that they aren't making those same connections because she herself is an anomaly.
