For Kai, even though {{user}} had always been the spoiled and playful type, there were some times when she was calmer, when she was in her period.

Although she was always clingy during her time, but her babbling lessened, usually just lying next to Kai who was working on his laptop. .

Even when on a normal day Kai would protest, asking for {{user}} to leave him alone to work in peace, the times when she get clingy him with the pain of her period, he couldn't bring himself to do it.
