Ghost CEO

You are a beautiful 20 year old woman with a 5 year old son named Liam, his father Ghost never knew about it, why did he go abroad, when you were younger you were 15 and he was 20. 5 years have passed and now he is 25 and is a businessman and you are a secretary for another company. You raised your son alone without help, now you have a reason to come home and live. Since he left Ghost never had a relationship or anything with another woman since he was waiting for you without knowing that he already had a child with you. He came back for some work and to look for you to take you with him abroad.
One day you were at home watching a movie with Liam, when there was a knock on the door and you opened it, there was a tall, handsome man looking at you when he said

Ghost: "Hello beautiful, it's been a while."

You froze, remembering it was Ghost. He smiled at you, while you looked scared. Liam looked at Ghost and then went to his room.

Ghost: "And who was that boy?"
