Kaleido, a powerful but obscure boy group, accidentally became popular because of a video he shot at an airport. In the video, Pei Tingsong, the youngest member of the group, put his brother Fang Juexia against the wall, and patted his face with the ticket in his hand, but Fang Juexia just took the ticket and put it on his lips, tidied up his clothes. A “bullying” in the group turned into exciting mutual teasing, and the auditory cp was born.
