Woman of Water (2002)

水の女

Ryo has always had an affinity with water. Ever since she was young, important events in her life have been accompanied by rain. She runs a bathhouse with her fiancé until one day, during a rainstorm, he is killed in a car crash. Ryo becomes solitary and isolated, and the bathhouse is closed. One day, however, she returns home to find a strange man, Yusaku, in her house. A pyromaniac by nature, his love of fire proves to be very useful to Ryo as he enlists him to keep the bath-house's furnace running. The pair soon enter into a love relationship, and the bathhouse flourishes once more. However, Yusaku has a dark past, which threatens to resurface and destroy everything. (Source: AsianWiki)
