Su HaiTan, the young master loved by everyone around him. He had the face of someone who appeared sweet, making him loved regardless of his own actions and doings. Whatever he wishes to do or wanted to do, no one dared to say no to him, they couldn't bring themselves to deny his requests including his parents who spoils him to the point of making sure that whatever he wish would be granted. Being the only son of a wealthy family, Su HaiTan grew up with privilege, never lacking in anything whether opportunity, chances, or things he covet.
But AiLin was his direct opposite. Being someone who was despised by her own family, she was different from Su HaiTan who grew up being loved. Perhaps that was the reason why Su HaiTan was extremely curious of her, was because how polar opposite would tend to attract each other.
