Rex, Sister Sha and An Qi returned to class on the same day, and Sister Sha's outfit was even more refreshing. Suddenly, all eyes turned from An Qi to Sister Sha overnight. For this reason, Angel felt very dissatisfied, and Rex also noticed Angel's weirdness. On the night of their carnival, An Qi went directly to Sister Sha to challenge her. Sister Sha lamented that she would not be able to spend the rest of her life peacefully, and Rex, who was eavesdropping on the side, also made up his mind to help Sister Sha. At this time, many new students were added to the class, including Sister Sha's close friends Ying Ya'er, Yan Zibing, Zhou Yuan and Nan Fengxue. Huang Qianzi is the younger sister of the evil sister who has a somewhat petty and wretched personality and believes that only fujoshi can save the world. Wang Yuewu, Dadong's sister and An Qi's friend, has been exploited by An Qi. Arthur's sister has long regarded Sister Sha as his sister-in-law, and helps Sister Sha deal with An Qi's Macy Wang Meisi. There is also Liu Lixia, who is cold and silent, and occasionally says some incomprehensible but hidden mysteries. What method will An Qi come up with to frame Sister Sha? How will Sister Sha and Rex fight against each other? When will the relationship between Rex and Dadong become clear? And who is the girl in the alley? (The last sentence is a bit useless...)
