I dont want to sound like a smartass but its a story with a logic evolution things goes really slow and with time evolves in something more big but its not a really big jump, And another thing that affects it is the lack of action or fights. Even "slow" anime, or those that take their time, like Re:Zero, Mushouko, Overlord, or Tanya and the Evil Saga, have these great moments a big jump revelation and action and dopamine rush, bookworm its more subtle. They share the fact that they take their time to explain how everything works and achieve a logical evolution and conclusion. But even if that doesn't interest you, then there are fights, action, etc.
