In the snowy mountains of Hokkaido, Yusuke has a grand proposal prepared for his girlfriend Saeko — but their journey takes an unexpected turn.

Saeko can't help but see Yusuke in Naruse, especially when his words eerily echo her late fiancé’s. Naruse experiences a terrifying flashback.

Thanks to a successful heart transplant, Naruse gains a new lease on life and surprising new habits. Later, a train delay leads to a fateful meeting.

Despite deliberately trying to distance herself from Naruse, Saeko runs into him at work. An unexpected typhoon leads them to share a touching moment.

Before the accident, Saeko and Yusuke briefly encounter Naruse on a rainy day. In the present, Saeko and Naruse take a day trip down memory lane.

As Saeko and Naruse come to terms with who the heart donor might have been, Naruse tries to learn more about Yusuke as a person.

While Saeko gets accustomed to her peaceful life at the coffee farm in Hawaii, Naruse comes to terms with his own life and makes an important decision.

Naruse receives a sudden diagnosis from his doctor. Meanwhile, Saeko musters the strength to make a bold decision and has an honest conversation with him.
