Another w.i.p but it's fluff

Luca[1] Was extremely happy to see Ryuu genuinely happy. He was glad that he could help, according to Annalise, this is how he used to act. greeting everyone with a tender smile
While helping him he Noticed some things.
The most interesting of them is that he bites his skin a lot, especially under stress.
While Ryuu claimed it was an old habit he's has tried to fix, he never saw any effort go into that.
Luca was told to hold a banquet of flowers that Ryuu was given by one of his teachers. and Ryuu went to the back of the greenhouse to see if he could find the type of flower to know what to do with it.
Even after all of this he couldn't understand his fascination with flowers, he even had the ugly looking ones. the only Cunclsion he came to was that flowers were...nice? (Nice? that's it? expand your vocabulary, me!)
