My main verse is sundrop incarnate ...  which means she has three moms,  one she doesn’t really want. 

Sungs keytar is a gift from his moms and is the only thing he has left to "continue" their existence

sung's electrokinesis is a rare case of kinetic fusing from maman's pyrokinesis and mother's aerokinesis. usually star keepers just inherit one elemental power from one of their parents.

Sung actually had a second brother who disappeared a long time before the moms died. He doesnt know if he's still alive or not but he presumes he's dead since it's been so long

Sung found ladyworld by accident. He barely remembers his mothers, but he could remember they were from some sort of wonderful planet. Woman planet? Lady planet? Feminine star? He couldn't remember the name of it for the longest time, until one day he just,, remembered. It was ladyworld. He visited it with the boys and being there made him feel,,, different. Though it was a good kind of different. He remembered where his family was from. He then wrote a song about the wonderful place

sung cried during wonder woman. partially bc he's softie who cries at all movies but mostly because he really related to it. Like... a woman from a homeland of oNLY other women overcoming her challenges and bringing peace to the Earth. It really reminded him of Ladyworld.... and also his moms. It just meant so much to him.

sometimes when sung and havve are alone, sung sings soft lullabies in their language that mother used to sing to them. havve doesn't understand it anymore, but he still feels a strong feeling of sadness and nostalgia in the back of his mind. it comforts him.
