Albedo was never a person who would go through all the trouble of starting a relationship, it was too troublesome. He hated the thought of rejection, since he knows how hard it is to build a relationship and how easy it is to destroy it. It's too troublesome. So he avoids talking to people, unless they need work done. But one day Timaeus, his apprentice brings in a new girl Sucrose, who has no idea what alchemy is, and is just there for the curiousity.
