This is some kind of mess, not a normal plot. I don't want to avenge Mila. I didn't stand up for her outside the college. It doesn't interest me at all. I didn't arrange with Bella to damage Mario's car (or whatever his name is). I have no desire to collude with Bella herself. But during the second meeting at Bella's house, she asks why I didn't show up at midnight yesterday, and the MC, for some reason, stubbornly takes the initiative to sabotage her neighbors party. And again he insists on revenge for Mila.
What are all these choices for if they do not affect anything?
