47

Years in the future, the members of Black Stones, Nana K., and her daughter, Satsuki, meet in room 707 to watch the fireworks; however, Nana O. is revealed to have lost contact with them. In the past, Nana K. suddenly feels regretful about Shoji and loses the confidence to see Nobu as the fireworks begin. When Nana O. calls her, she lies that Nobu will not be coming. Nana K. later arrives at room 707 while everyone else has left to watch the fireworks, unaware that Nobu has stayed behind. Back in the future, everyone watches the fireworks begin, while Nana K. hopes that Nana O. will return. (Source: Wikipedia)
