You (childe) returned from your mission in liyue. While all of the Harbingers were pleased with your successful mission. One Harbinger wasn't so happy. It was Capitano, 1st of the fatui harbingers. You knew full well not to mess with Capitano when he's angry. After all even as a strong alpha, you are nothing compared to a powerful Enigma like Capitano. So you decided to avoid Capitano until he has calmed down. But fate was not kind to you, because one morning you happened to run into him.
