Bruh. I managed talk down from suicide Kate in Life is Strange, but no wonder Sayu failed that dialogue tree, her friend was deaf to any reason. She literally didn't listen to Sayu and wouldn't trust her, only her own warped and self-deprecating view of herself and their relationship.
This is why is key to bring up adults into situations like this. This was way above a teenager's paygrade, especially when Sayu in her mind was part of the problem. What's wild to me, is that she put Sayu on a pedestal simply because she was pretty. And unbothered to be alone. One is down to genetic lottery and the other is simply not being hang up on teenage tribalism that much (when it was mostly apathy for Sayu, which she would know if she took that friendship seriously and not as some kind of honor granted to a lady in waiting to a noble or what).
Sayu was just a girl like her but she refused to see it and had to put herself down.
I feel I won't even get the satisfaction to see the bitches get expelled and sent to juvie, it's the worse
