Hyacine's arc genuinely felt like a very uninetersting character with very little background and story getting stretched out one patch long while Hysilens felt like a very interesting tragic heroine with a real complicated backstory who got condensed into half, maybe at best 3 quarters of a patch because she had to share one with a bootleg Red Saber Hoyo arbitrarily decided to be her romantic interest.
If this doesn't convince you how much of a hack Shaoji is, nothing will.
>Durrr you only felt that because unlike Hysilens Hyacine wasn't a pagbait
Huge SEA market contributing to HI3's success as an exclusively yuri ship IP aside, it is very much possible to write an heir with a compelling backstory no pagbaiting required, as shown by Cipher and Tribbie.
