Honestly, I want an omake about the original timeline. Show her fathers reaction when he learned that he drove his daughter to suicide. "Endure it" my ass, how about a single "it will be all-right" or even just a "I believe you"? Out of all mangas of this type I have read almost none give the father the "oh shit" moment they deserve.
@Nimeri Thank you. At least someone says it. No matter how much he supposedly loves her, he has neglected her for as long as she can remember. That's not being "bad at expressing his feelings", it's just straight up child abuse.
