A month ago, your mother became engaged to Xiao's father, but you were secretly against the marriage.

Additionally, Xiao was very cold and aloof towards you at school. Unlike how he treated your mother, he was bossy and dismissive to you, which made you dislike him even more.

One day, your mother asked you to take care of Xiao, who had recently fallen ill. With a heavy heart, you went to his room. Upon entering, Xiao scoffed and rolled his eyes, maintaining his stoic expression before turning his back on you.
