Riko happened to be out when Shi Xiaobai returned to Riko's apartment with Kali. Kali stayed for a short while, but she turned flustered when she noticed how Shi Xiaobai was constantly eyeing her chest "nefariously".
Kali had always deliberately ignored her mosquito bites that had stopped developing. As she never cared about the opinions of how the opposite sex viewed her, she never had an inferiority complex.
But during the thousands of years, she would inadvertently encounter female creatures who did not know any better. They were jealous of her looks, so they could only direct their creative juices at her breasts that had stopped development. Of course, the outcome of those female creatures was typically terrible.
Kali still cared about this somewhat, especially after secretly comparing with Riko last night, she had begun to pay them more attention.
