Li Shu didn't know why she had no memory of their agreement. However, with this stone pendant, she now understands why Chen Jianmin insisted on marrying her in that world.
With their promise and this pendant, it seemed impossible for her to distance herself from him. From his recent behavior, she knew what he was thinking.
Although both are only twelve years old now, in four or five years, their families will surely start looking for their potential spouses. So, he might be trying to get closer to her so that they can be together more easily in the future.
After coming to this conclusion, Li Shu let out a long sigh. She was in poor health and might die young. She couldn't be selfish and become a burden to him.
She carried the stone pendant and walked outside. Standing on the balcony, she looked at Chen Jianmin, her eyes full of guilt and gratitude. After hesitating for a while, she finally called him, "Jianmin."
