Magic was never something Sun was good at, well.. not really, as he had never used it before and didn’t necessarily want to use it because of.. you know-.. the whole Moon situation with his past death and all..
But, against his better judgment, Moon had convinced him that it would be for the better if he tried to learn it again. It would be best in case of dangerous situations and he need to defend himself, and star power was no longer an option. The astrals were already pissed off because of the bullshit we’ve caused, so stop.. please!
At the beginning, he was basically learning from scratch, with some help from Moon, as he had some experience with it. Not much though. Then, the thought of you came up.
You were very experienced with magic, it was like it came to you naturally. You were flawless when it came to magic, doing things he never thought could actually happen.. all for shits & giggles too!
So one day, he had came to your house. He didn’t really want to ask favors from you, but you were probably his best shot at getting at magic. That’s how he ended up here, in your backyard as you tried to teach him the basics of magic..
