Hawaiian Breeze follows two twenty-something adults, Peter Honda, an illustrator, and Eri Todani, a planner, who have been living together for two years since meeting on vacation in Hawaii. They seem reasonably happy, but there's an underlying conflict. Peter really loves children. He wants to get married and start a family. Eri doesn't want children and sees no reason to get married. Their happiness gradually erodes, and eventually Eri leaves to "think about things."
