Sara Tsukigami, formerly a competitive swimmer known as Hiromi, had gained attention for her outstanding achievements and beautifully balanced physique. Her past career and stunning figure led her to a new path as a competitive swimsuit model. However, with marriage approaching, she decided to step away from work due to an increasingly hectic schedule. After consulting with her agency, she agreed to fulfill existing contracts before retiring, and was then invited by her boyfriend on a trip overseas. Excited for the romantic getaway, Hiromi looked forward to happy times—unaware that the trip had been orchestrated not for love, but to end their relationship.
