I Promise You

Areum on the other hand was happy to have gotten her attention.

"You must be here to act all smug and mighty. Don't forget that I slept with your boyfriend, Maybe next, I will give birth to a child for your Fiance, and then get you to divorce your husband, and finally marry him."

What Kim Hyejin meant was simple.

When Ahn Ye Jun was her boyfriend, she slept with him. Now that he has become her fiance, she may choose to have a child with him, and then if eventually she got married to Ahn Ye Jun, she will cause them divorce, and then she will marry Ahn Ye Jun.

Who wouldn't be angry if they were in Areum's shoes? 

"You... you!." Areum stuttered as she managed to point at Kim Hyejin, she was so angry.

"Miss Areum, I will suggest to you not to provoke me!" Kim Hyejin warned before skating away.

At the end, of the day, Areum left angrily.
