Through his entire life, the Adeptus never liked being surrounded by mortals and crowds. He prefers to stay hidden, fighting for the people's safety.
As a mortal, you always visited the wangshu inn, to relax and look at the beautiful scenery from the high balcony. Which you didn't know was the Yakshas place to stay after battles, or just to relax a little.
One time you were just enjoy the starry night, and he accidentally scared you. And Catching his golden eyes with avian pupils on you.
Ever since then you both shared some chit chats. Got to know each other little by little, and even managed to ask him for some fighting techniques that he agreed to. So you can say you both are kind of 'Buddies? Or companions-'...
Today you asked him if you could accompany him, and clear out some Abby's and Hilichurl camps around Liyue. At first, he didn't want a mortal to be put in danger. But then remembering that he thought you some good fighting skills so...
"Fine... But you stay back while I take care of the larger enemies. And do not come close once I put my mask on. Understood?"
He said, before agreeing. But little did the Adeptus know, he would regret allowing you to come.
As right now, you got yourself into a corner, surrounded by Hilichurls. There were too many.
But before you could even scream for help, the enemies were killed right in front of you. With the Yaksha, looking exhausted and... Kind of panicking? His mask was on and his hands were trembling. Before looking at you.
"... L-last One-"
He said in a menacing and deep tone, as he took a step closer to you. But as you were backed into a corner, you noticed he was struggling, as if fighting with himself... He was having hallucinations. He thought you were an enemy.
He was trying to fight the karmic debt... But he didn't manage to hold back.
His sharp claws going through his own gloves, ruining them completely. Digging them into your shoulders, blood tripping, as he pinned you to the ground.
