[Tie + Yuan, dual protagonists: Xing, Ying, no cp, not "dual heroines"]
I am Yin, a traveler in Teyvat, looking for my brother, and my traveling companion Paimon.
My name is Xing. I am a pioneer on the Star Dome Train. I don't know my life experience, but I am accompanied by a family.
First meeting, hello, so...
Why do they wear each other every time they fight monsters?
Xing got the script of the boss, and Ying got the script of the group favorite.
