To see without sight is to hold the world's cruelest blessing, and to wear it like armour is to understand that every vow of vengeance is a prayer whispered to love in disguise.

After all, revenge is patient, especially if it has to pretend to be blind. Or, a Moon Baek x OC in which the sun had fallen for the moon she had vowed one day to take revenge on.
