Sora, Koushiro, Mimi, Jyou and Takeru had been brought to the Digital World, where five monsters were waiting for them. A mysterious force acts to destroy the place and everybody living there. Although none of the children had been very close to each other before, they must work through their differences and clashing world views in order to survive. Every new challenge will force each of them to face their own demons. In this universe, Taichi and Yamato do not become chosen children.
It's not simply a divergent timeline AU, as the denizens of the Digital World themselves are significantly different from their canon counterparts. The Chosen Children and their partners, however, are the same people they were in canon.
Beware, spoilers for The Song of Love listed below.
The Song of Love contains examples of
- Alien Abduction: When the children first arrive in File Island, Mimi and Koushiro believe this to be the case
- Big Damn Heroes: As Mimi and Jyou are about to be killed by Drimogemon, they are saved by Leomon
- Black and White Morality: Devimon feels this way, and Takeru comes to adopt it after his partner, Angemon dies
- Cut Lex Luthor a Check: Justified- Leomon has a healing liquid but it's so rare he has to use it wisely
- Dysfunction Junction: With the exception of Mimi, all the kids have serious angst in their pasts
- Sora's father spends most of his time away from home and her mother is emotionally distant, causing Sora to feel unloved. She also believes that she will disappoint everyone and let them down, a feeling made worse by her role as de facto leader of the group.
- Koushiro is adopted, and has internalized a lot of the stigma against adopted children, causing him to see himself as a burden unless he is being helpful. He does not believe he deserves to annoy or worry other people.
- Jyou feels overshadowed by his older brothers and his average grades in spite of his near constant studying. He believes he is a failure, an average person who will never amount to anything.
- Takeru suffers from loss and abandonment, starting from his parents' divorce, and exacerbated by his partner's death.
- To some extend the early relantionship betweeen Jyou and Gomamon is very frosty due that both guys have strong pride
- Fantastic Racism: Since the most hated and feared digimon had once been a Patamon before he became powerful and destructive, some digimon still fear all Patamons and will kill them on sight, especially since digimon reborn after they are killed, albeit without memories of their past life, so any given Patamon could actually be the feared tyrant of ages past
- The Fundamentalist: Leomon seems to believes that digimon under the effect of the black gears are just evil but he was being lied to and is horrified when he finds out that they're innocent victims.
- God Is Evil: The Spirit of the World, who functions as the god of the digital world torments Koushiro with images of his biological parents and tries to convince him to commit suicide.
- Gray and Gray Morality: All characters in this story believe they are doing the right thing, even those who want to destroy the world.
- The Heart: Mimi, as the most emotionally stable member of the group and the one everyone likes, fills this role
- MacGuffin: Leomon has a very rare liquid that heals everything
- Morality Kitchen Sink: Characters range from well-intentioned but misguided, to seeking revenge, to employing terrible means to achieve their ends. The Chosen Children are trying to be the good guys, but that's rather hard when the people they oppose are also trying to be the good guys
- Unreliable Narrator: Whenever someone delivers exposition about the past, they leave out some key details, often because said details are painful to recall
- We ARE Struggling Together: The Chosen Children bicker a lot more than they did in canon
