Initially believing his application had been rejected, he is surprised to receive a last-minute acceptance just when all hope seemed lost. Upon moving into the property, however, he quickly discovers an unexpected twist regarding his new living situation. Every other resident sharing the house turns out to be a female upperclassman attending the exact same school. What begins as a simple housing arrangement immediately transforms into something far more complicated. Surrounded entirely by older women from his own university, the protagonist finds himself thrust into an unpredictable daily routine. The shared residence becomes the backdrop for a thrilling and chaotic student life, filled with constant romantic tension and frequent encounters revolving around the showroom's luxurious baths.
