Reiko is a 28-year-old that works at a housing maker. She suddenly gets dumped by her boyfriend Koichiro after 5 years together. Before that, she was happy because she was able to balance both her career and love life. Thanks to the break-up, the string that equaled stability in life snapped in one swoop. The solution she comes up with to her problem is to fall just totally head-over-heels in love and ride the "wave" of love as far as it will take her.
