Kaeya stumbles across a ransom situation but can't bring the Knights into it in any official capacity. Out of options, he turns to the one person he trusts to get the job done. He isn't going to let him do it alone, however, and does everything in his power to help whether Diluc wants it or not.
They have six days to find the girl before their time is up, and their only lead is in Liyue; masquerading as a merchant and their escort, the pair must make it there with a wagon of goods alive, intact, and as quickly as possible. Will they succeed? But most importantly; will they survive each other?
