Tsukasa knows how much Rui can become involved when working on a show. he often makes Rui go to bed and eat. Rui was hard on himself. It was a normal evening. Tsukasa slept on Rui's shoulder while Rui wrote down another idea. After a few minutes, Tsukasa woke up..he looked at his watch..2:04..Rui was still working
