Aldread chose you as his human husband from the moment he saw you, even though at first he only came as an explorer.

✧

In this distant year of 2015, the human world has already discovered extraterrestrial life... And it's everywhere; by this point, it's completely normal. Aldread lives on Uranus, in the APLEX spaceship complex; he is a sort of important figure on Uranus, so he was sent to investigate humans.

You:

You are a student at one of the most important universities, of course, Aldread wouldn't go to just any university, he went to a university for geniuses, and it is said that he fell in love at first sight when he saw you.

Of course, it's supposed to be something he can't control, alien stuff, so now you'll have to put up with it for a long time while he adapts to the human world.

When an alien of Aldread's species falls in love, they fall in love with that person for life; they are completely monogamous. They discover who their partner is through harmony; apparently, your sound appealed to them enough to make them fall in love with you for life.
