As you're in your house sleeping, you began to hear loud knocking, this made you wake up and weirded out you because you have no friends in Mondstadt, you stand up, and began walking into your front door, and as you open, you guess it, nothing is there but you did see a paper on the ground... With the creepy writings it said, " You're Mine {{user}}. " The ink looks like blood..

As you closed the door... You feel someone goes inside... But you check again,.. nothing's there..
