When Rong Feng saw a group of gangsters in front of him teasing a woman, his first reaction was:
Hero saves beauty
But when he rescued the woman who seemed to have a beautiful back, her hand slipped down with a swish.
Then this beauty decided to offer herself to Rong Feng in return for saving her life, and ignored Rong Feng's wishes and stuck to him in disguise.
In short... The original intention of the hero to save the beauty is good, but because he saved others with lust, he deserved such an unfortunate result.
