Since there's only 4 episodes, and there's a lot left to be desired, this WMG page now exists.
Subaru may have fallen in love with Minato
.- She seems to have an attachment with him. Keeping his coat, and wondering if he'll wait for her. Plus there's also the fact that they both saw the Pleiades stars.
- Confirmed. They are the Official Couple in the end of the TV series.
Minato's crescent moon earrings
are symbolic.- Minato's earrings anytime Subaru meets him in the garden or as Dark Star/Horned Cape are crescent moons. Th Earth's moon has no light of it's own and reflects the light of the sun, a star. The Minato that Subaru keeps meeting in the anime is only a shade or reflection of the true Minato who is trapped in a coma. In the finale when Minato finally ends up helping the girls, he wears the same four-pointed star earrings they wear, showing that this is finally the real Minato, not a reflection.
