In my opinion, Cheng Xiao improves as the drama progresses. Give her scenes a chance, she's seriously so pretty & I love her action stunts. Her scenes with the ML and her brother don't call for exceptional performances, but their interactions are in the very least cute. She isn't Zhang Xueying, Ren Min, or even Deng Enxi level, but she's an idol expanding her prospects, Song Qian, Wang Yibo, Yiyang Qianxi all took time. Restrain from saying she doesn't deserve the role she earned through auditioning; every project will contribute to her growth as an actress. If every chance goes to the same actress you've enjoyed in the past, the drama world will be so dull; I was interested in this drama because the casting looks refreshing.
I think there's just 24 episodes and an 11 min special with Yongyi and Xiao Wu. The special is so cute, it shows their friendship and gives satisfaction to their characters. Hope it gets subbed along with the official episodes.
