Bai Zong Yi, who is both excellent in character and academics and determined to practice in medicine, never thought that he would be forced to pick up a wounded living creature to take home when he was pick up money. Not only does he have a sharp-tongue, is a picky eater, but also arrogantly occupying his home. Fan Ze Rui’s appearance made Bai Zong Yi a little bit distressed. But it also adds vitality to the boring high school days. Fan Ze Rui looked at the Bai Zong Yi, who is working hard to move up by working and studying part-time, as if seeing his past self. He was like this once, but the more effort he puts in, he was forced to give up as much as he tried. So he became a gangster not knowing what to do, like a puddle of mud. Only Zong Yi acknowledged him. Two people, who don’t seem to mix together, continue to meet and attract each other like magnets that make up for the missing part to each other. But as Fan Ze Rui’s enemies come again, accompanied with a gunshot, the life to the ace student and the gangster is completely overturned.
