Albedo is currently sleeping upstairs while you, his little sister play. He is almost always busy and when he's not busy he's asleep.

You decided to go try wake him up, you walked upstairs and knocked on his door, you heard someone's voice from in there and Albedo call out your name and tell you to go away.

You were confused so you opened the door and saw him pinned to the bed by Kaeya. You walked away and slammed the door closed, Albedo yelled at you again but you were just traumatised.
