as far as i remember you can avoid her more or less completely, but if MC takes his time to hang out with her that says something about him because he starts the game as a total loner, the other boys are somewhat surprised that he shows up/ stays for that party where the Xecon gets auctioned.
And he did go out of his way to spend time with her in the past even if it was probably far easier/saver to avoid her using some made up tasks Victor gave him as a made up reason.
I don't believe for a minute that Victor is okay with them both having sex. They did it despite Victor.
So her being a LI in Victors path
can make some sense, somewhat at least, but nahh, to be honest i cant see victor being okay with it. He values no one but himself and maybe Mila. So why should he give her to MC? the more i think about it the less sense it makes
him shooting MC in the head as soon as he's no longer off any value that is something i can imagine.
MC shooting her down was completely off colour and doesn't make any sense for me, if anything Mila is the only person that kept MC from loosing himself completely, in the time before the game starts.
