My Love from the Stars

University teacher Mitsuru Toyama hasn't aged a day since coming to Earth 400 years ago. 3 months before finally heading home, actress Tsubaki Sasahara moves in next door. Her loud midnight singing disturbs Mitsuru, who has 7 times better hearing than humans. When he goes to confront her, he realizes just how hurt she's been. Meanwhile, Tsubaki's childhood friend Hiroya Uwajima proposes to her.

Mitsuru sees an ominous dream of a stiletto floating in the water. That night, Tsubaki crashes into his room, drunk. He finds her purse and discovers an old photo of her, looking exactly like the girl he saved 400 years ago. He had saved another girl 12 years ago with the same face, and realizes that it was Tsubaki. He sees her wearing the stiletto from his dream, and warns her never to wear them.

After saving Tsubaki, Mitsuru hears a disturbing conversation between Masaya Uwajima and his secretary. Next morning, Reiko Bando is found dead in the sea. A suicide note is found, and witnesses say she and Tsubaki had been quarrelling. The media blames Tsubaki for Reiko's death. To hide from reporters, she escapes to Mitsuru's room. There, she finds his diary titled "My Last 3 Months on Earth."

While sheltering Tsubaki, Mitsuru's friend Seiichiro Kurachi comes to visit. The reporters leave, and Tsubaki goes home, but she's fired due to the gossip concerning Reiko's death. Meanwhile, Masaya discovers that Tsubaki has the USB containing his dark secret, and comes for it. Mitsuru saves her and finds a camera hidden in a gift from a "fan." Hiroya once again proposes to the desolate Tsubaki.

Tsubaki's mother and brother come visit to find Tsubaki and Mitsuru quarrelling. She introduces him as her new manager. Mitsuru hears that Tsubaki had rejected Hiroya's offer and is relieved. Later, Tsubaki is in shock to find out Yukino had taken over her lead role. They meet the next day, and she's hurt by Yukino's words. As she leaves, Mitsuru spots a man dropping a vase on her and saves her.

Mitsuru saves Tsubaki from falling off a cliff using teleportation. Tsubaki swears she saw him, but he claims she couldn't have. Meanwhile, Masaya presumes that Mitsuru has the USB and wants it back. Ono and Natsume investigate Reiko's death and find a suicide note in one of her shows, the exact one she'd left behind. They realize the suicide was staged, and Tsubaki's suspicions are cleared.

Tsubaki confesses her love to Mitsuru, but he doesn't give her an answer. He then tells her to meet her at the park, but instead of Mitsuru, it's her father who'd been gone for 12 years. Unbeknownst to Tsubaki, Mitsuru had set it up. Meanwhile, the detectives tell Tsubaki that her suspicions had cleared, and Tsubaki tells them how Reiko had been dating Masaya. Hiroya also begins to suspect Masaya.

Mitsuru reveals to Tsubaki that he's an alien, but she doesn't believe him. He tells her that he despises her, but in reality, he's pushing her away as an inevitable parting awaits. Meanwhile, Hiroya finds out that Masaya's wife had been locked up for the past 5 years. Tsubaki is offered a small supporting role, but is hurt by the cold treatment. Mitsuru arrives, saying he came to protect her.

Mitsuru tells Tsubaki that he only has 23 days left on Earth. Tsubaki suggests living together. They try to make nice memories together. Mitsuru then decides to stay. Hiroya saves Risa, Masaya's wife, and hears that Masaya had killed his other brother Fumiya. Hiroya asks Mitsuru for help, but Mitsuru refuses. Hiroya confronts Masaya on his own, but as danger approaches, Mitsuru suddenly appears.

Mitsuru decides to stay on Earth, and he and Tsubaki go on a trip. That night, Tsubaki suddenly tells him that she's breaking up with him and marrying Hiroya. Heartbroken, Mitsuru prepares to leave Earth, when Hiroya comes over. He tells Mitsuru that Tsubaki was lying to make Mitsuru go home as he would die if he stayed. Just before it's time to go, Mitsuru opens up to Tsubaki how he really feels.
