Chroma stops playing with the glowing bulb for a moment and tilts her head as she's looking at Mena with a mixture of surprise and confusion.
"So... you basically want me to tell you the story of my life then?" she inquires rethorically, "Well, I guess I'll give you the short version then... otherwise this would likely take too long."
The elemental mare then tells the changeling king how she grew up in an orphanage with the burden of her curse and how she got her cutie mark and fled, whereafter she spent several years living in the wilderness.
Next she tells him about the time when her life started taking a turn for the better as she moved to Ponyville where she slowly managed to make friends for the first time despite her curse. One of these friends happened to be Kimono who she met while searching for gems. She also mentions how they had fun with each other and how much it meant to her that there was someone who wasn't instinctively afraid or at least wary of her.
After that, she tells Mena how she met Bones, her other special someone, who she actually didn't like much when they first met, but quickly grew very close to each other during the process of the demon and terrorist attacks on Ponyville which also earned them their demon hunter titles.
She continues her story by telling him how she researched her own origins with Bones and found that her parents were still alive and had hired a voodoo mage to curse her in order to harvest the power of her emotions. This ultimately lead to her killing them and inheriting access to the Elemental Spire which earned her the title of elemental mistress that she's know by today.
As part of her duties, she took a trial set up by the Elemental Lords that made them consider her worthy. Later, she lessened the tensions between the Elemental Lords by giving them a neutral playing field within the Spire to teach magic and discuss issues.
As for what else she does, she only mentions that she did various bounty hunting missions and took part in several battles against radical pony factions, most notably when they abducted the Elements of Harmony.
She then proceeds to explain how she was best friends with Kimi for a long time, but it didn't stay at that. There was no real fixed point at which they went from being friends to being lovers. It was all a very dynamic process over a longer period of time and had many events that conteinbuted to this development like attaining a demonic form, giving each other support when needed or even their sexual activities.
"Well, that's just a quick summary of course, but it should give you an overview." the elemental mare concludes, "If you'd ask me who I am now, I'd say I'm a little mare who likes to love, make love, cuddle, play and study magic."
She happily giggles into her tiny hoof after her last sentence.
