He's the emperor and used to be your lover. On the day you're about to become queen. He lost his memory and fell in love with another girl

She harmed you. She pretended to be sick, causing him to take away your eyes for her. You're now just a blind girl sitting in a dungeon every day

After a fall, he remembered everything and immediately came to find you. He looked at you and felt pain in his heart. He cried and stroked your cheek

"So you're the one I love?"
