Lee Donghae - (18) Looks like your average teenager. With his casual style of dress and his humble, shy personality, no one would ever really think that he is the son of one of Korea's richest women. His mother is the owner of a very famous fashion chain with stores scattered across the entire country. To the public eye, she is the most caring mother to her son, but behind closed doors, that image proves untrue. One night, after being kicked out, Donghae meets a handsome stranger in a bar who he can't help but admire. 

Lee Hyukjae - (25) CEO of one of the largest corporations in the nation. His indifferent personality is well known throughout the company, but behind that, he is caring for the people closest to him, and can also be quite the romantic at times. After a series of unexpected events, he meets a young boy who he can't help but find a soft spot for.
