I See Stars (Tomatt/TomMatt/Mattom/MattTom)

A mysterious alien, who looks surprisingly human, crashes to Earth one day during a meteor shower. Housemates Edd and Matt are determined to help heal and educate this being, so that he comes to see Earth is a wonderful place. And the alien, who's name is Tom, notices that Earth probably has the best view of the stars that Tom has ever seen. After some time spent together, Tom and Matt grow close, and Tom is faced with choices he doesn't know how to make.
