It has been raining in Tokyo for three consecutive years. The once prosperous city has gradually been eroded by stagnant water, and a damp haze has enveloped everyone's life. Hodaka, a young man who fled his hometown, and Hina, a girl who was once a girl, built a warm little home for the two of them on rainy days, and lived an ordinary life full of fireworks.
However, the disaster caused by the continuous rain became more and more serious, the water level continued to rise, the order of the city gradually became chaotic, and the criticism of Haruyo also hit again, blaming all the suffering on Haruna. Rumors spread like shadows, putting the two of them into fear and trouble, but also made their bond stronger. Old friends reunite and lend a helping hand to clarify the truth and dispel misunderstandings. In times of crisis, villagers help each other and convey warmth. Hodaka actively participates in the rescue and protects his homeland. Hina also regains the faint echo of Haruyo in her dream.
Even though the heavy rain has not stopped and crises are everywhere, the two people have always worked side by side, resisting the wind and rain with love, and waiting for the glimmer of light with perseverance, firmly believing that one day the rain will pass and the sky will clear up, and the sunshine will once again fill this city that carries their deep love.
