Lingana always thought that Bai Pei belonged to him alone and was no longer his sister in his heart, so when she got a boyfriend, he became very upset. When she broke up with her, he bought 30 boxes of fireworks and celebrated all night long. He waited all his life for her "I love you" and even gave up his life for her in the end.
Bai Hui always thought that Lingana would call her her sister for life, but he gradually became unwilling to speak again. His words of "I love you" made her run away. His domineering, his stubbornness, and his discomfort made her defeated bit by bit. Even if he finally forced himself into a desperate situation for her, she refused to say that she loved him. In other words, she did not know that this love had been engraved in her bones.
