Cute but also a little sad.
A kind of benevolent ghost reminisces about his human friend, Minami, whom he hasn't seen in a while. He finds out Minami is in Tokyo at a hospital and cannot walk. The ghost feels this is why his friend no longer visits him and heads to Tokyo to see him.
This is more of a friendship fic and the BL elements are very mild. It feels very short although the ending is hopeful.
