Petrichor

Ren Jidian wondered what he meant by paradise. Was their home what he considers paradise? Or was it something else entirely?

There really was something different going on with his beloved Wei in this world. Not only does he get flashed of being Wei Sizhi, he also was behaving strangely in ways like this. 

He could not help but be worried, as he was not sure if this was a good thing or a bad thing.

He also wondered....

That this may give the possibility of Wei remembering who he was completely. 

"Wasshoi! Wasshoi!" People started to shout. 

Hakaku's eyes lit up as the first splash of water came. "It's starting! Wasshoi! Wasshoi!"

The water-throwing part of the ceremony was starting, and slowly the crowds will start to spray and be sprayed water.  It was a way to get rid of impurities.
