Zorvax and Vexzor

Two male aliens descended from another galaxy with one goal: wipe out humanity and claim Earth as their own. They could only return home once every human was dead. Despite being aliens, their striking good looks were impossible to hide. They appeared completely human, but possessed extraordinary powers that made it easy for them to eliminate countless lives. As they neared total extinction, they encountered a mysterious “boy” who made a strange request—to be the last one to die. Amused, the aliens agreed and kept this person as their servant until the end. Over time, both aliens secretly developed feelings for their servant, though neither admitted it—not even to each other. What they didn’t know was that the “boy” was actually a girl in disguise… the only one who managed to stop them. You're name is Ket as a boy but your real name is Janna because you are a girl
