Astronov and Neptunia is a romantic pairing involving Astronov and Neptunia.
Back in High School, Neptunia had a huge crush on Astronov, similar to Tootie's crush on Timmy Turner. Astronov didn't have any feelings for her and preferred Wanda, who was in love with his bully, Juandissimo, and later her husband, Cosmo. One day, Neptunia asked Astronov to the prom, but Astronov refused and explained a very nasty complaint about her, which put Neptunia in tears and she angrily slapped him, then took off. After graduation, she wasn't seen again. Years have passed, and after flying past a beauty pageant in Fairy World, Astronov went inside and take a look at the bachelorettes. The last one came by and caught Astronov's attention. When the pageant was over, Astronov quickly rushed to the last bachelorette and introduced himself. Little did he know, it was the formerly nerdy and new stylishly beautiful Neptunia, who still held an ill-will towards his High School love interest. Astronov quickly apologized for what happened back at the prom and decided to make it up to her. After a few dates, despite their different I.Q. ranks, their relationship grew stronger as soon as they got happily married.
