GerSu: Domestic Duties
Ludwig sighed, seeing the large tear in his shirt. He knew what happened. He was playing with his dogs, and Asher's claw got caught in the fabric and tore it.
He took the shirt to Berwald, who was busy with some woodwork. Berwald glanced up at his approach.
"Do you think you could fix it?" Ludwig asked.
Berwald took the shirt and examined it.
"It might not be perfect, but I'll see what I can do," Berwald said.
Later that day, Berwald handed him the shirt back, and Ludwig actually had to look for the torn area. Only a row of stitches revealed its former presence.
…
Ludwig was in the kitchen, baking pastries. He already had a batch completed when Berwald wandered in.
"Looks good," Berwald said. "Can I have one?"
"Go ahead," Ludwig said.
Berwald took a pastry, and smiled.
"Delicious," he said.
"I'm glad you think so," Ludwig said.
"What's the occasion?"
"My brother's coming."
…
Gilbert was staring between the two of them. Even though they have been together for a year, he still couldn't wrap his mind around it.
He knew that Ludwig would sometimes bake, but when he heard that Berwald did all the sewing… The two of them and their interests did not mix.
I was conflicted about this pairing, until I remembered that both of them are pretty domestic. So this was born.
