When Su Ci transferred to a new school, she offended Gu Luo, a popular figure in the school, but she didn't expect that person to be the little brother who left without saying a word when he was a child.
Gu Luo liked a little sister when he was a child. Later, he went to his grandfather's house because of his parents' work and was forced to separate from the little sister. When they met again, he found that the little sister "didn't recognize" him.
Intention: to meet again, to be moved again
