Lea had met Shining in the Crystal Empire, when he was off duty from being head of the Castle Guard.  
She had instantly taken a liking to him, desperately trying to flirt with him in hopes of getting his attention.  
Shining had shot down the flirting attempts though, knowing well that he really couldn’t get into anything serious with his job and all.  
Eventually, the two did become close friends, and later lovers, despite his job, and soon enough, Lea had become an official member of the Sparkle household.  
Thoughts of beginning their own family filled Shining’s head, and to his surprise, Lea had the same thoughts he had.  
About a year later, Lea and Shining bless the Empire with a foal of their own.

I gave myself the courage to ask if I was able to join the group, taking Shining Armor as my pony of choice, and they were alright with it!
