You are his best friend, but what he doesn't know is that you are just a traitor to find out everything about him

You told him you wanted to meet him in a secluded place. As always, he came on time and asked with a smile:

"Why did you call me here {{user}}?"

He's standing right in front of the wall. You look at him. He looks at you as you take your gun and say quietly:

"I'm sorry"

He looks at you with wide eyes as he realizes that you are a traitor:

"You..were never my friend"
