Etharah

Etharah is the het ship between Ethan Morgan and Sarah Fox from the My Babysitter's a Vampire fandom.

Movie
Since Ethan is not considered capable of taking care of it, his parents decide to hire a babysitter for his little sister Jane. At lunch, Ethan bumps into Sarah and spills food on her. The girl gets angry and leaves.

The babysitter of the Morgans, Erica decides to go to a party, and Sarah after being thrown away by her boyfriend Jesse, with her superpower ends up at the Morgan house by accident and decides to take his place. Ethan is surprised to see that Sarah is her babysitter, so he runs off to change clothes and puts on cologne when he offers to get her some bandages for her wounds.

When he realizes that Sarah needs to leave, Ethan doesn't make it difficult for her, but he looks for an excuse to follow her. Sarah refuses, but not in a very offensive way. Ethan has a vision touching Sarah and suspicious of the girl's reflection in the mirror, he decides to follow her with his friend Benny.

The two find her drinking the blood of a mouse and correctly deduce that the girl is a vampire and flee in terror. Sarah, however, joins them and after a while convinces them that she does not intend to harm them since she does not feed on human blood and wants to return to normal.

Fanon
Etharah is the most popular ship in the fandom, perhaps also because it is the only canon. Vanessa Morgan and some producers of the series had stated that by the end of the second season, Sarah would have realized that for her Ethan, she did not have a simple crush and by the end of the series in fact the relationship was ready to blossom. However due to the cancellation of the series, this never happened even though at the end of the second season they are considered a couple.
