Why didn't Chunzhong choose Ba in Big Fish Begonia?

Many people say that Chun chose Kun because of love. I think the early stage is love, and the later stage is out of my own guilt. But I only have feelings for my brother.

Maybe he fell in love with Kun when he first met him on earth. When two teenagers of similar age, the heart is the first deer to bump together, and there is no spare tire calculation. But after Kun's death, Chun only felt guilty about Kun and wanted to save him. When Kun came back to life, Chun just wanted to protect him. Let him grow up and return to the world. Toona sinensis killed Kun and mistook guilt for love, so he wanted to trade his life for his, thinking that this is the eternal love in the world. She didn't know that it was Ba who sacrificed the most for her, paid the most and loved her the most. I think cartoon's emotional transition to Kun is natural. Love, but not complete love.

But why not choose Ba? I think it's because for Toona sinensis, she is more like a relative, like a brother, so no matter how much she has done for her, she is not ignorant of her good, but she can't deceive her feelings, nor can she deceive her feelings. Her refusal was out of a sense of responsibility. Toona sinensis's heart has always been Kun's and has never wavered. At first, she and Kun were different in species and belonged to different worlds. If there is no accident, she may just keep Kun in mind, occasionally reminisce about the short-lived beauty, and dare not go against her fate, because she still has relatives and the responsibility of taking charge of begonia flowers. So some people say that it is irresponsible for her and Kun to secretly live in an abandoned building. I don't agree with her. With the back of her sitting by the well and the weather changes that showed her emotions at that time, I always felt that she was thinking, blaming herself, wondering if she had made a big mistake, and thinking about the words "never clear" of Lingpo. Thun, she's growing.

Such an independent-minded girl, love has never been her whole, or even nothing can be her whole. She thinks more and further. Including those who finally saved her with the rest of her life, she is trying to assume the responsibility of choosing Kun. Because Toona sinensis and Kun are destined to be entangled for life.
