The Three Clock Keepers arc HanaNene analysis:
The first thing that I (and kouxD) noticed in a part in chapter 26^^, is that Hanako seems to be bothered about something
and that he seems a little down unlike his everyday happy and cheery spirit.
and later after that- hanako suddenly brought up a warning for kou to make sure mirai doesn't touch nene.
And it is later on revealed here^^, that Nene is going to die within the next year-
and even though hanako seems to not have much of a care of nene's lifespan- he's just hiding it, because that's hanako's habit, to not show anyone his thoughts or true feelings.
He also said it makes no difference- but it does- and it hurts him. He even confirmed in the Picture perfect arc that he truly wanted to save Yashiro, because her life matters to him- her happiness matters to him, and it's all that matters to him..
And in this panel^^ we can see a bit of hanako's true feelings in his eyes. He also said that he tried to make nene enjoy the time she has left, even if he said just before that someone else's life doesn't matter to him...- but what hanako doesn't know is that nene also needs hanako, and that even if she doesn't get to live longer, she just want to be with him, because...
..they just want to be together...even just for a while.. because.. they need each other.
