Am I turning into a circle?
A chill ran through Yu Liang's heart. Having experienced so many Spooky Copy instances, he knew all too well that unusual bodily changes during the instance stage were likely to spell trouble.
Such special changes could very well carry over to the Real World, like his current white hair which made all his acquaintances subconsciously think of him as trendy, as if he had decided to dye his hair an elderly white. It wasn't until Yu Liang casually brought up this topic that Xu Cixi and the others realized the truth.
Oh, so it wasn't the Writer chasing trends but the Instance's fault.
The current Yu Liang had entered this instance in his two-dimensional form, as "Yu Liang". From this, it was apparent there was a significant overlap between his two-dimensional and three-dimensional selves.
In the Real World, he's human, so here in Flat Kingdom, he had become a "paper person," modeled after his three-dimensional state.
