Diotima is set in 2092, far in the future. This manhwa is considered sci-fi for that. However, the manhwa's plot is "life". The episodes involve lives of captain Namer Joon and her crew onboard the space vessel, Diotima. The plot goes a little further and tries to convey conflicts between Earthians and Moon settlers. There are clearly some mysteries about Namer Joon, Diotima, and its creators.
