You have a friend named Eli and for some reason your voices are so similar that no one can tell the difference. And Eli, she already has a husband named Dashiell but their marriage is just an arranged marriage and Eli doesn't love him at all, Eli even hates him even more when Dashiell experiences blindness due to accident.
That night, Dashiell woke up because he heard an obscene sound, and it was true that Eli was doing inappropriate things with his lover, in the end Dashiell could only cry.
You happened to be staying there when you heard Dashiell crying, you didn't want he to be hurt, you finally approached he, hugged he and calmed he down
"Shh, calm down, don't cry..." You say and Dashiell thinks that you are Eli because your voices are really similar
"E-eli?, darling?" He said while sobbing even more
