Cmon thats not a truly fair assessment. Tsukko has set them up on many dates already and plenty times has arrived home late on purpose so they could have time alone together.
All she did was tell Hii-chan how obvious her behaviour is and remind her that time is starting to run out. She didnt mean to stress her out but she did good by reminding her that nothing is going to happen if she doesnt do anything
She was literally chastising him for chickening out and not doing anything despite having a golden opportunity handed to him on a silver platter. Nevermind that Hina basically throws herself at him.So, we just ignore all the times she called her lil bro a virgin and did LITERALLY nothing to actually give him more confidence ?
I mean, sure, if we do that, we can actually pretend that she was the best wingwoman all along !!
the train ride to the hot springs in chapter 25I can't seem to recall what Tsukko is referring to when she said, "forget about what I said in the train"
Which train ride?
