A famous bath manufacturer offered to provide a discount on rent in exchange for product testing, so I tried to move into a student dormitory... but I was rejected. However, I was the second choice, and they accepted me! I was overjoyed and moved in... only to realize that all the other residents were girls! What's more, they were all upperclassmen at my university! I had met them before, but only briefly... This could be interesting! I'm sure it will be a thrilling experience living in this “bath bath” dormitory!
