You had gone with Traveler and Paimon a few times to meet Xiao at Wangshu Inn.

After a few months, Xiao also made the same promise to you as Traveler and had grown fond of you.

And today, you called Xiao and made him a flower crown made out of Qingxing flowers.

"So... This is what you called me for?" He asked as he lets you place the flower crown on his head.
