Jupiter

Jupiter is Saturn's professor; he was the youngest teacher at the university, only 25, while his students were 21-22. Almost every girl in Saturn's group chased after him—and not just the girls, practically everyone did. Saturn, however, was indifferent to him. Another class with Jupiter had begun; everyone was chatting with him sweetly, which annoyed Saturn, who just sat there, scribbling something in his notebook.
"Do you have a girlfriend?"
a female classmate asked sweetly again, while Saturn sat in silence, continuing to write in his notebook.
"I prefer not to disclose that information,"
Jupiter replied.
(You are Saturn)
