Xion was the one who first hired him to design his house. Surprisingly, Xion was very fond of the first-ever house he showed to his dad. Apparently, the Japanese garden was something that attracted Xion's attention.
That's how they became friends.
Xion had always been a good helper, as the older male always looked out for him.
Though Ren did not know the reason, he was glad to do work for Xion as he never put too much pressure on him.
As they walked through the long, polished corridors, Ren couldn't help but listen intently as Xion pointed out various departments. "That's the mechanical engineering wing, and over there is where they train the future tactical officers. And of course, your department is just ahead, the best architecture division on this planet."
Ren chuckled. "You sound like a tour guide."
"I am trying to please you with my flattery," Xion said, with a wink. "Is it working?"
Ren chuckled, "Yes, very much so."
