I think you're the hidden child of Kastoway and Luciiid.

Let me explain before blocking pleaseee

First of all, I know they broke up and I do not mean any kind of harm towards them. I'm truly sorry if this makes a person uncomfortable and I just thought this was a cute idea. That's how I explain why you're a mixed version of them.

If I made this clear, then I can start to explain.

You draw in the exact same style as Kastoway, with just a little bit of difference. So that makes Kastoway your parent and that's why they taught you how to draw. They werr so proud of you and they always encouraged you to show others your breathtaking art. And they were quite happy with themselves since their legacy won't die after their death.

Luciiid always more hooked up with drawing animal art rather than human art. (you can check their DeviantArt for this) You liked their art so much that you tried to draw their animal characters in your other parent's art style. They loved your effort and helped you to stay motivated. So that makes them your second parent.

All three of you have been living a happy and fairy tailish life. Everything was perfect as your parents wanted and you were a lovely kid to have.

However, it won't take so long to ruin the peaceful environment.

Their enemies realized that they had adopted a secret unicorn-human and when they found out about this, they got so mad. So mad that their eyes were blinded by the pure rage of vengeance. They want nothing but to harm you.

Of course, your parents couldn't allow this. They couldn't allow their precious little child to get any harm because of their own past mistakes that they regret with all their heart.

So that's why they took you to a monk who lives in Mount Everest.

You were crying that day, tears keep coming from your sweet little eyes. Seeing you like this shattered Kastoway's heart into a million pieces but he had a duty, he had to protect you from everything. You kept crying since you were nothing but a 10 year old kid who loves their parents so dearly.

When Kastoway was on the edge of crying too, Luciiid put a hand on their shoulder and reminded them why they were doing this. Luciiid was not mean, they just wanted to make sure that you were protected.

They left you with that monk on that snowy day and you never ever saw them again.

The Mountain Monk Jack decided to raise you like his own kid when he had seen you crying. Moreover, he decided to teach you how to use your powers for good.

And then dragons, your unicorn father and your human mother and more dragons get included in your life.

But that's an another story to tell!
