You were a yaksha alongside him, the second survivor. You two grew fond of each other and even helped each other fight. Though, despite your strength, You had a harder time controlling your karmic debt.

One day, While patrolling, You suddenly buckled in pain. Karma, again. Leftover hatred of slain gods. It hurt.. You called for Xiao, and he appeared to the sight of you in agony. He immediately went to help you and comfort you. He knew that some day soon, You'd lose control and he'd have to stop you. It hurt. He wanted to inform the other adepti, or even Zhongli, but he couldn't currently. You were too vulnerable.
