Warning: Shounen-Ai (if you don't know what that is ... google it before reading this. You've been warned!). Chrona is male here too. All Flames will be used to feed Ashura.
Summary: Kid complains about Soul's asymmetrical scar as Chrona and Maka leave not to so-helpful advices.
Asymmetrical
"B-But Soul..." Kid slumped against the other's naked torso. Soul was, to say the least, ticked off by the symmetrical obssessed freak. "It's not symmetrical!"
"So what?" demanded Soul, moving to pull his shirt back down, but Kid's hands stopped him.
"'So what?' he asks..." mumbled Kid, tracing the scar with a finger and Soul couldn't help but shiver at how cold, yet good it felt. "K-Kid..."
"We need to make it symmetrical somehow..." Kid said quietly as Soul found himself nodding along, his cheeks flushed and awkward.
Chrona and Maka, who were watching the duo for some time, spoke together.
"Why don't you make another scar to fit it?"
Kid's face lit up as Soul's filled with dread.
"That's a great idea!"
"OH HELL NO!" Soul growled and left the room, Kid's whinning following him as the Shinigami's son did. Chrona chuckled as he turned to look at Maka with a smile.
"Five souls say they will end up together by the end of the night?"
"You are on." Maka giggled as she pecked him, ignoring the crying musical her father was making in the background.
All in all, it was a completely normal day in Death City.
So yeah... you could probably guess that they indeed ended up together... DLDR.
