So this is love

 "What the hell are you talking about?" Chang Jun snapped. This mer, he was joking with her, right? He was lying to her. He had to! What did he mean by that he adored her sister and whatnot? That was just rubbish. 

If he had loved her then her sister would be alive and not dead.

Ji Weimin covered his face with his hands, he curled his fingers as if he was in sheer agony. He heaved a breath before dropping his hands to his sides. "I was going to return to her. I was going to come back, once I broke free of my mother's clutches I was going to give an answer to your sister but she—she left before that." 

His voice choked up at the end of his words causing Chang Jun to stare at him in shock and disbelief.

"You are lying! You never—you never said it!" Chang Jun was so agitated that she held the bars that had an electric current running through them.
