She is the most beautiful child in town, but a poisonous poppy. As long as she can climb up, she is willing to do anything, including selling herself.
He was the arrogant man in everyone's eyes, and he truly bowed before her. Willing to do anything for her including selling himself. That's how it is to love someone.
She kept hurting him, thinking that he shouldn't delay this promising person. He has fallen into an abyss from which he cannot return and cannot be redeemed, so why bother dragging someone who loves him into the water? She is no longer able to love, her heart has already been given to the devil.
He watched her keep hurting her but was helpless. The more he tried to help her, the deeper he fell. He loved her, but he couldn't give her the most basic protection, even though in the eyes of others, she was the one who surpassed him, a top student. But he knew that if it weren't for her, he wouldn't have been able to find such a good way out.
They just love and suffer like this. She wants him to live a better life but doesn't know how he can live well without her. He wants her to be saved but doesn't know that not being able to watch him succeed is her biggest regret.
