>>10597847So, she actually expounded upon this in a members stream. Basically, Takamori, i.e. the tsundere-chase relationship, was something that she and Mori thought up while they were in Japan, and it worked alright for them while that was still the case.
However, now that Kiara has left Japan, their offscreen interactions are much less frequent. That being the case, neither of them want to continue "Takamori" as the character relationship, but as their normal relationship, which Kiara cited their offcollabs as exemplifying.
So basically, the "Calli, I love you!" "Shut up kusotori, you're so annoying" aspect of the relationship is dead.
Hope that helps clear some things up. :)
