In the first episode of the second season of Horizon Records, Kazuki's dialogue at the end hinted that they had a relationship but could not be together for various reasons. Cheng said,"I've been thinking about what we would be like if we really had a chance to be together. Will we be like ordinary people?" "Maybe," Dawn replied. But we are not ordinary humans. We had feelings and beautiful memories between us, but those beautiful memories have disappeared." Cheng said,"Do you mean we should start over?" "No, I mean we should forget the past and start anew," said Xiao. This dialogue also hinted that there had been emotional entanglements between Seiji and Akatsuki, but they could not be together in the end. The conversation between Seiji and Akatsuki also revealed the hypocrisy and complexity between them.
