CRAVEN

: having or showing a complete lack of courage : very cowardly

     Mark was speechless for a moment but this time, it wasn't because of curiosity like the first time he met her but because of Ji Sun's arrogance and over-confidence. He even forgot that he has a sprained ankle and was sitting all the time.   And  this  time  too, he's  sure  that  this  girl  wasn't  really An, his first love. They might look the same, but their attitudes are a hundred and eighty degrees different. An is sweet, kind and 'real' while this girl tries so hard to look  innocent  on-cam but is the worst  for him when she's not in  front  of cameras. He had totally changed his impression of her because of this accident. 

    Mark met a girl that exactly looked like his first love. But that girl's the girl he didn't expect to be. He thought she was  just the  same  person  and as sweet yet brave as his first love, but no. So, Mark thought that maybe they were just really two, different persons. 

     Jisun was the opposite of his first love. Well, at least for him She was conceited, but deep inside, she's coward... Craven. She wanted to get rid of that attitude, change Mark's impression of her and gets everything  planned. 

               But, what if it doesn't turn out the way she wanted?  

"You're the worst."

"Stop acting like you know everything. You don't know me."
