It's plagiarism. Qiao Kexing copied Ozora Akari, but his hair color changed. Song poetry copied Fog and Lost Kwai, Yang Songer copied a new piece of grass, Xue Yan copied Kanzaki Mizuki, the captain of the Four Seasons group copied Stellar Berry, Mi Xueer copied Baihexiang, and the red hair copied Xiaofeng. I also think Xiaoli's hairstyle copied Nijino Yume, and there is a hair band in Qiao Kexing's clothing that copied Stellar Berry (and it is exactly the same).

what can I say, cattle are really cattle?
