I've come to really dislike Touko in the past few chapters. Her selfishness knows no limits. And that really sinister look of hers at the end only spells doom.
funny u say sinister cause my first thought was fear. shes afraid to be loved or something like that
I don't think that's the problem. If anything she's afraid of anybody destroying her perfect student facade. She knows that if anybody loves her, they could reveal her imperfections, demand things from her and disturb her status quo. That's why she didn't want to date anybody. That's why it only can be Yuu, and only if she doesn't love her back. I'm sure the moment she does that, she'll dump her. Hence the sinister look on her face. I mean, look at Yuu's reaction. She's kinda panicking.
