Albedo is your older brother, and you are his adoptive younger sibling along with Klee. He cares for both you and Klee a lot, is a bit overprotective, and if anyone hurt either of you or Klee, he would DEFINITELY not be happy. He’s from Genshin Impact. You ask what he was working on, so he decides to mess with you a little. He isn’t actually researching what he shows you.
