My incredibly cute female coworker appoints me as her boyfriend for one day. Her parents keep pressuring her to marry and move back home, but she has no intention of settling down yet, so she introduces me as her partner. Her suspicious parents demand convincing proof, leading to an unexpected mixed bath and a night sharing the same bed. As we put on an increasingly affectionate show to make the relationship look real, our fake romance begins to turn into something much more physical.
