accept Nathan's proposal

Nathan looked at Casey who had her back to him, making him afraid that his proposal would be rejected.

"Casey, I want to marry you, make you my wife, be Clara's replacement...I will always take care of you, always be there for you..let me make you my best friend, my love, the queen of my life... We can be like when you were in Clara's body," he pleaded.

Casey was silent with a feeling of uncertainty, feeling that what had happened was not what she expected. just being a woman who is prioritized as a substitute, she doesn't think it's enough for her, enough to guarantee her happiness ... she is so hesitant to accept this impromptu proposal even though Clara always asks her to be her successor.

"Casey..."

Casey immediately turned to Nathan, looked at him seriously then shook her head.

"I can't," she said.

"But why?" asked Nathan disappointedly. "Don't you love me, you always say that you have a guardian angel….Isn't that a guardian angel is me?"
