The movie opens with a young Mamoru on the roof of a hospital: he hands another small boy a rose. The little boy thanks him and says "No one has ever given me a gift before". He then dissolves into thin air as he vows to bring Mamoru a flower. The movie flashes to the present day. Mamoru, Usagi, and the rest of the four "Inner" Senshi are at a botanical garden. Usagi tries to steal a kiss from Mamoru, but when he notices that they're being spied on he walks off outside alone.
