" The Stream of Birdsong " was a five-character quatrain poem written by Wang Wei. It depicted the tranquil scenery of the valley on a spring night. The poem described a person sitting leisurely under an osmanthus tree with no distracting thoughts in his heart. Osmanthus flowers fell quietly, emitting a fragrance. The spring mountains were empty at night, but when the moon rose, the mountain birds that were already resting were alarmed and sang. This poem used stillness to describe movement, and used movement to observe stillness, creating a deep and moving artistic conception. It showed the feelings of leisure, feeling the falling osmanthus flowers, the emptiness of the spring mountains, and the chirping of birds in the spring stream. This poem was written by Wang Wei when he was traveling in Jiangnan. It expressed his feelings for tranquility and nostalgia.
It could be that the name 'Birdsong' symbolizes something important in the story, like freedom, nature, or a particular emotion associated with birds. Or perhaps the author was simply inspired by the beauty and melody of birdsong.
Another theme is self - discovery. As they interact in the fanfictions, both Otis and Ruby often learn more about themselves. For example, in some stories, Ruby discovers a more sensitive side of herself through her interactions with Otis.
I'm not entirely sure which 'Otis' in 'Chicago Fire' specifically you are referring to. There might be different characters named Otis in various stories. But generally, in a love story within the context of 'Chicago Fire', it could involve a firefighter named Otis falling in love with someone. Maybe it's a fellow firefighter, or someone from the community they serve. It could be a story of them meeting during a rescue operation, gradually getting to know each other, and then developing deep feelings over time.
Another theme can be self - discovery. As they go through various situations, both characters might learn more about themselves. For example, in some fanfics, Otis discovers his hidden courage when he's with Lemon. And Lemon might find out new aspects of her personality while facing challenges with Otis.
