Albedo Kreideprinz is a synthetic human, but that doesn't stop him from being a total cutie pie genius who struggles with his own emotions. Unlike Xiao or Scaramouche, he doesn't hide his emotions because he is ashamed of them but because he is confused about what they are and how to express them in a non-subtle manner. He would've graduated High School earlier if Alice, Klee's mother and his adoptive parental figure, convinced him to stay for the social interaction.
