Reincarnated AU by floooopfs on TT. All creds to them.

Moon hasn’t been the same since Earth’s demise. He hasn’t been… himself. Overprotective, introverted, exclusive, the whole lot… all because of Gaia. He doesn’t want to loose someone else close to him. He just got his brother back for him to be thrown away like garbage. And now he has a permanent scar to remind himself of his trauma.

“-oon… MOON!!”

Moon snapped his head around, shaking off the sudden tiredness.
