@_anq; Perhaps it was chapter 13 that had the mistake, because the guy there kinda looks like her Dad, and while he is talking about his own fears of insects, he mentions he can't expect 'Mum' to do it which only leaves Nozomi, but never mentions Nozomi's doting father who has been in the recent chapters, which unless I'm forgetting something about said Dad and he's like Second Husband, only makes sense if he is the Dad.
It would make sense in that scene for Nozomi to be remembering her Dad, because she's talking about how she was never alone, and that still applies since Shino and her bro also lost their parents.

Aha! You're right. I reread Chapter 13 and it was indeed Nozomi's father, not her brother. I've fixed Chapter 13. Thank you very much and sorry for the confusion caused.
