After the vegetative husband wakes up, he wants to marry his first love

I developed mutism due to childhood trauma.

My parents, ashamed of my condition, forced me to marry my sister Olivia's comatose fiancé, Ethan, in her place.

After three years of my devoted care, Ethan miraculously woke up.

But the first thing he did upon waking was to demand a divorce.

He mistook Olivia for the one who had cared for him these three years, declaring he would marry no one but her.

Later, I overheard his best friend explaining to him that it was actually I who had cared for him all this time.
