Our ML was going through a trauma as he's deprived of his legs at the age of 4, his legs are amputated 3inches below the knees. His family used to be just like any another happy small family of three members, before the tragedy,

His mother is also suffering from psychological stress , depression that's why she divorces .

Bei Chuan uses wheelchair, at the age of 10 he tried using prosthetic limbs but due to some reasons he stopped using them a year later.

FL= Our Fl is a year and half younger than the Ml . When she turns 20 some rich chae boel decides to use her as a shield wife to protect his real lover from harm ways...

So we can imagine that our Fl is like a fairy, . Her family financial condition are lowest in company to other families residing in the community.

She's a bit dimwited, and a slow learner whereas Our Ml is Child Genius.
