Was I that important? (Gray x Reader)

You are a powerful wizard. You posses all the magic of 4. Ice Make. Water, iron, and fire dragon.

Age 13:
You trained Gray on his ice powers after his original trainer had "died" ((the ice shell)). After a few months teaching him little tricks that you have learned. You said you had to leave and that you would be back to teach him more. But while you was with Gray he developed small feelings for you.

You found Natsu too and also helped him out with his magic a little bit. You tried to help him control his anger. After a few months you told him that you didnt know how to do much with his kind of magic, and that you would be back when you got stronger, and promised you would help him too. He also developed feelings.

And lastley lucy, found her much younger because she was a run away. You took her in and took care of her for a while. Eventually you realized you couldnt take care of a little child and you told Lucy you had to leave and that you would be back one day.
