I have no idea why everyone is getting so angry at the poor girl. She tried to talk about it, it really isn't her fault she was interrupted both times. It is possible that the apology may cause some misunderstanding, but that should be solved the next time as well since obviously she's not going to just run away now.
Um, maybe because you don't have to accept that you've been interrupted? The chapter ends with her just sending Hinoka home like she's disappointed in her. Poor Hinoka, that must be devastating.
Ah, yes, that's why she was the one apologizing... It really rather seems the opposite, like she's worried she may have upset Hinoka instead.
Despite me being able to accept that Tsukushi is confused, it doesn't change the fact that she hurt the girl who went out on a limb and kissed her. You don't need to have an interruption-free moment to just say "we'll talk later."
But I do agree that these words were missing there.
