Nana stared at him for a while and asked, "You still love her, right? I know she was your ex-girlfriend."
"No!", Jianyu said with a glint of hate in his eyes. "It's over between us. I-, he sighed, "I admit that seeing her like that did evoke some remnant feelings of our past relationship. I know you can't believe me, but I swear there is nothing between us now. You can say that I got the closure I was looking for all this time. Please don't worry. We won't have anything to do with each other from now on."
Silence.
She sighed, "I understand. When you see your first love in such a terrible condition, no matter if you have broken up, I think anyone would have behaved the same way."
And who am I to judge anyway? When even I am still affected by him, she thought.
Jianyu took her hands in his and genuinely said, "Thank you, Nana. I promise I will never let you suffer again."
