Here comes an unusual couple! Efrew the Mareanie and Carola the Corsola~!
They meet each other when Carola traveled from Hoenn to Alola to study art, Efrew was being bullied by a group of wishiwashi (despite him being part of an intimidating race, Efrew is very shy and other water types take advantage of it). She saw the situation and didn’t hesitate to defend him. He was quite surprised that a Corsola helped him, but Carola don’t cares for stereotypes and they quickly became friends and lovers.
Fun fact: she tried to fool her parents by attempting to pass him by a as a shiny Corsola:
I didn’t worked, but they played along for a couple of hours. Carola and Efrew are happy together in a very healthy relationship, not matter what people says
