There's nothing much that can be done, honestly. Someone's gonna get hurt, it's just a matter of who.

I can't turn down Sayori's confession, because I do love her. But I can't be with her and with Monika at the same time, and if I don't choose Monika... Well, you know what's gonna happen. Unless I could stop her, but I don't want her to go to jail either.
But then there's Yuri. I really like her too, and she really needs...just someone. I think I can actually just be friends with her, but still...
And then there's Natsuki. I can't say I love her. I wish I could, but in reality I just feel bad for her, that's all. I could call CPS on her father, but she then might end up in a foster home. And who wants that?

So, real or not, The Literature Club is truly a place where no happiness can be found.
