Yeah, only character that actually got WORSE after the 1.0 transition was her. Went from partner in crime to kind of a bitch. Still hoping for a hate fuck with her, but seems unlikely to happen before he puts the game on hold. Still a shame that the entire sleepover that was still can't happen in the new editions... though. Few orgasms should calm her down.
Thing is, Ako was never really a friend or a wingmen, it's just her intentions weren't clear yet. I recently replayed the game from the very beginning, and she was obviously planning to tackle you from day 1, only it was under the pretex of being friendly, and everytime her plans got disrupted by the MC, she flipped more and more showing her true nature.
She sets you up with Emily on a date, because she knows your past with Alice, notices her reaction on the possibility of you dating Emily, which means you're an obvious threat for her to get Alice, and this way you can get out of her way easily.
Then she helps you with Martin if you choose that route, but that's only because you're interests are aligned, and she doesn't want anyone else to get on their hands on Alice, and doesn't know about you and her as of yet.
Later, when she approaches you with her offer, that would only give you the option of peeking (duh) initially, she's already quite desperate as she turns get her drunk while becoming a borderline rapist and you talking Alice into lesbianism. Note that by that point she's already acting high and mighty with you. If you decide not to play along, she flips on you for being a "pussy", which is rich since she expects you do all the work and cover the costs, for only a little reward, and when you tell her the deal changed she flips again, but still being on her high horse for literally no reason.
And this tendency only continues when it comes to Lily, basically her trying to butt in something you built up by yourself, even more when it comes to the lesbo cheers, where again using your network, relationships, and where you do most of the groundwork, she expects you hand over everything with almost nothing in return, then when it is foiled again, as the MC is who he is, and the girls simply like her more, she again gets desperate and tries to corner you.
Akos latest move when she busts the Emily relationship in front of Alice is nothing but another episode of her behaviour from day 1 actually, not something that got ruined during the course of the game. And this is why I'll never understand the fandom around her...
