University teacher Mitsuru Toyama hasn't aged since coming to Earth 400 years ago. Months before finally heading home, actor Tsubaki Sasahara moves in next door and disrupts his life.

Mitsuru has an ominous dream of a stiletto floating in the water and warns Tsubaki. When he sees an old photo of her, he realises that he saved her 12 years ago.

After saving Tsubaki, Mitsuru overhears a disturbing conversation between Masaya Uwajima and his secretary. Tsubaki is blamed for someone's death in the media.

Mitsuru's friend Seiichiro Kurachi comes to visit; Tsubaki goes home when the reporters leave, but she's fired because of the gossip.

Tsubaki's mother and brother visit to find Tsubaki and Mitsuru quarrelling. She introduces him as her new manager. Later, Tsubaki learns that Yukino has taken over her role.

Mitsuru saves Tsubaki from falling off a cliff using teleportation; Masaya believes that Mitsuru has the USB and wants it back.
