Oh i remember that face izumi's friend had. Someone looked at me just like that when i was in middle school. If this face hurts as a drawing, then imagine how painful it is in the reality. I can tell. It's the most horrible feeling i ever had by far.
Me too. I said mentally "oh no..." when i saw that face but couldn't take my eyes off it and turn the page.
Still, it doesn't make any sense for her to fall for Tadokoro san at this point
Why not, Tadokoro is adorable and has been super nice to her, even when she hasn't deserved it. Now, I don't think she's actually gonna try to get with her, because A: Kirigaya is not really self-aware that she's into girls (yet), and B: even she knows better than to summon the wrath of Nikaidou again.
And as you say, she already has a girl, even if she doesn't realise it yet.
