If in the future, he had to make a choice between Lan'er's life and loving her, he would choose to let her live. This way, he would hold true to it.
He hoped that he would never have to face such a choice.
Hearing Si Mobai's words, Feng Tianlan's body stiffened. "Will your head continue to ache if you do not become Wu Ya back?"
"I don't know. Maybe it is the case. After all, Wu Ya loves Yunyi deeply." Si Mobai looked down at her. "What do you hope for?"
"Mobai," Feng Tianlan exerted some strength and struggled out of his embrace. She looked up at him seriously and said, "If it will always hurt, then I hope you can become Wu Ya again."
"I don't want to be Wu Ya. I won't be able to love you anymore." Si Mobai's heart was warmed by her words. Switching positions, they would have done the same for each other.
Although she said so, he still hid it from her because he did not want her to be sad.
