It’s a good thing construction workers aren’t paid by hours here

"Is everything fine?" I scooted closer to Lesta, who was in the middle of examining the formation arrays across the pond.

He crouched next to the wall, ignoring me for a few seconds. There was a monocle with a vision enlargement spell over his eyes, just like what Izzi used when he was working with his component. I counted until twelve in my mind, before he finally answered.

"Good so far," he said while moving his gaze to another formation. 

I glanced at the workers, who let out a small sigh of relief. They still looked anxious though--would be, until Lesta deemed everything was okay and gave them a pass. If there was an error or something was considered dangerous, they would have to change a whole section, not just one formation. After all, every spell here was connected. 

Reminded me of every time Eruha examined my homework. 

Was it because they were lovers?
