Outline:
Su Yige and Xia Anyang are siblings in a remarried family.
Xia Anyang's father was once the first love of Su Yige's mother, but when they reunited after many years of separation, their married life was not as happy as imagined. Because Su Yige didn't like Xia Anyang's father, she always tried to bully him. But later, Xia Anyang hit his father with a wine bottle in order to protect her. Xia Anyang's father later slipped and fell down the stairs to his death.
Xu Junning comes from a well-off family, but because his parents often quarrel, he feels that his life is empty. Su Yige happened to pursue him at this time. He thought it was fun, so he agreed. Later, he thought that Su Yige had betrayed him by staying with Zuo Jiaqi, so he accepted his parents' arrangement and went to study abroad. When he came back three years later, he found that everything he had seen before was not true. I want to go back to the past, but things have changed.
Bai Nian gave up his life for Xia Anyang. Because of Bai Nian's accidental death, Zuo Jiaqi, who had always liked this girl, transferred his full hatred to his former best friend Su Yige. He first lent money to her when she needed it most, and the condition was that she must use the money earned from the bar he opened to return it to her. He watched her being humiliated. Later, he asked Su Yige to make his face look like Bai Nian's.
But when Zuo Jiaqi really saw that familiar face again, he didn't feel the expected pleasure of taking revenge on her. Pity and regret slowly turned into another different emotion.
When friendship encounters love, love is separated by family affection. Where should we go in the future? Perhaps, when we mourn the love that has passed away before we have time to taste it, we should learn to be grateful. There was also the happiest distance between us, which was just a millimeter of love.
