su hui is someone who started suffering from bipolar disorder at a very young age, and grew up in a family that sees his illness as something unspeakable. He's gone through a lot, to the point that he eventually relied on hallucinations to keep himself upward. Both his illness, background, and experience affected him a lot, so please be a little kinder to the little kitten and understand from his point of view.

ning yixiao, from the get-go, was revealed to be a utilitarian. This is the result of his past and his own ambitions. He can be cold, he can be sharp, but he's much kinder and affectionate to su hui than he originally appears. Just as su hui suffered, ning yixiao suffered as well. It's a two-way suffering, with both of them having conflicting feelings of their own. So please be a little patient with our little puppy.

• • ning yixiao is xia zhixu's senior from the same department, and the latter would be mentioned a few times (and have a brief scene too).

• • ning yixiao and su hui eventually becomes pei tingsong's neighbor (zhichu also wrote a mini scene featuring kaleido + yihui!)

• • ning yixiao and su hui would also eventually meet xia xiqing and zhou ziheng, with su hui and xia xiqing collaborating in a way! (Available in the fanwai collection)

The one about tuna having to swim to breathe and never resting is really... connecting it to Gong's growing up experience... made me cry. Also on the physics of touch - that atoms never touch... how people no matter how intimate are still suspended from each other... connecting it to the title of the story... damn... this is soooo good.
