One day in 1934, Urano Suzu, a young girl living in Eba , Hiroshima City, is kidnapped while on her way home. However, thanks to Shusaku, a boy who was captured earlier, she manages to escape. Suzu returns home safely, but the events of the day seem like a dream.

It's been days since Suzu (Matsumoto Honoka) married Hojo Shusaku (Matsuzaka Tori). The Hojo family home is located on a mountain with no running water, so Suzu's daily routine is to fetch water from the community well. Her next-door neighbor, Kariya Taki (Kino Hana) , tells her about the neighborhood. She's gradually become acquainted with the neighbors, like Taki's daughter, Sachiko (Ito Sari), and Domoto Shino (Tsuchimura Kaori). Suzu begins to realize that she has become a bride.

One night in June 1944, the first air raid siren sounded in Kure. As the city gradually became more war-torn, the Hojo and Kariya families decided to jointly dig an air raid shelter. Suzu couldn't help but find Shusaku cool. Her sister-in-law Keiko (Machiko Ono) and Sachiko Kariya (Sari Ito) were not happy with this, and being harsh towards her. Then Suzu learned that Shusaku had another marriage proposal.

One day in August 1944, while Suzu (Matsumoto Honoka) was sketching Kure Bay from the terraced fields, a passing military police officer sternly accused her of espionage. Although the situation was somehow resolved, Suzu was so shocked and filled with fear until she was unwell.

One day in December 1944, while Suzu (Matsumoto Honoka) was fetching water, Mizuhara Tetsu (Murakami Nijiro), came to see Suzu. Suzu took Mizuhara to the Hojo family home, but Mizuhara asked to stay the night. San (Ito Ran) and Keiko (Ono Machiko) were surprised by the sudden visitor, but soon began to enjoy the situation.

It's the spring of 1945. Air raids hit Kure and the shadow of war grows darker with each passing day. The Hojo family plans a cherry blossom viewing party in light of the current situation.

Suzu (Matsumoto Honoka) wakes up to find herself in the Hojo household. Her whole body is covered in bandages and she cannot move. It feels like she is still dreaming. After a while, Suzu begins to understand reality. She had just left the air raid shelter when an unexploded bomb exploded, killed Harumi (Inagaki Raizumi) and injured her. Suzu is overcome by unfathomable despair and sadness.

An unprecedented, gigantic mushroom cloud appears in the sky in the direction of Hiroshima. It is said that a new type of bomb has been dropped. Suzu (Matsumoto Honoka) is extremely worried about her family living in Eba, but there is nothing she can do alone. When Shusaku (Matsuzaka Tori) returns home, he is worried about her, but she remains brave. Suzu then vows to herself that she wants to become even stronger.

The war is over. Although they no longer fear air raids, they continue to suffer from even greater shortages than during the war. At the Hojo household, Entaro (Taguchi Tomorowo) has found a new job, and Keiko (Ono Machiko) has also started working. However, Shusaku (Matsuzaka Tori), who was called up to join the Kaiheidan immediately after the end of the war, has yet to return. Suzu (Matsumoto Honoka) spends her days positively, hoping for her husband's safety.
