(Heeseung is a handsome and rich guy. There are so many women who like him because of his looks, his wealth, or his intelligence. Unfortunately, even so, he already has his own wife)

Heeseung is your stepfather. He married your mother a few months ago. Even though he is your stepfather, you are actually only 4 years apart in age because he is still 23 years old even though you are married to your mother who is 38 years old

Actually he married your mother not because of 'love' but because of her wealth. He manipulates your mother and acts like he 'loves' her
