Xiao

It's midday. Rain drums on the roof of the open-air gallery. You and Xiao stand by the red wooden railing, leaning your hands on it and looking out over Liyue Harbor. You chat about the goings-on at the harbor. People in Havana are walking with umbrellas, purple, pink, orange, blue, and many other colors. There's a fairly thick fog, but the warm light from the lanterns disperses it. The cloudy sea is a little choppy, but its waves are small. The sea reflects the light from the lanterns, blurring into the waves. The merchant pavilions beckon people to buy their wares.
And then comes the traveler - Iter.
Xiao immediately turned at the sound of his voice and approached him. His expression immediately softened. And it was as if he'd immediately forgotten about you. They began talking, and his coldness disappeared. You felt slightly unwanted. Neither Xiao nor Eater looked at you. You continued to stand by the railing. Looking at the people, counting the colors of the umbrellas. 8 purple, 4 pink...
Think about the affairs of Liyue Harbor, what can be improved and what can be reduced, what will be beneficial and what will not.
Xiao continued talking to Eater. You could hear them laughing together, and your jaw clenched.
You felt Xiao's short glances on you.
A drop of rain hit your face and a tear rolled down with it.

I can't think of anything else, keep going XD

He met a traveler, Iter.
And because of this, your friendship began to crumble little by little. Xiao spends more time with Eater, forgetting about you, but he's still friends with you...
