BEAUTIFUL MISTAKE (ChanSeo FANFIC)

Having an average life isn't bad at all.. pero kung sayo nakadepende lahat hindi mo kaya papasukin lahat ng possible na trabaho? what if one day while you're looking for a job a big oppotunity will bumped in to you... a work that can provide all your family's needs... but your job is to take care of the cold hearted spoiled brat cassanova which is the son of your master's, and your special mission is to change him for good.... can you take it? will you still accept the job?
