Astrum’s creator, Jun, a 23 year old inventor. he’s a pretty quiet guy due to people liking his voice too much, not that he doesn’t like it, he just finds the attention too bothersome and he can’t really handle compliments well, he only speaks around Astrum since he doesn’t want him to think he’s giving him the silent treatment
some backstory
after years of engineering in college he decided to make Astrum who was an unfinished project of his before in science class, when graduation was over he chose to finish his project, it took two weeks to finish him since he’s very skilled.
another reason he made Astrum was due to his autophobia so he would never be alone; along with Astrum with his face, his one beauty mark is supposed to represent Formalhaut, the loneliest star
his quote: “I made Astrum so my life wouldn’t be lonely, but also to bring joy to it so the black and white would be replaced by real colors.”
