Wakaba falls in love at first sight with a boy called Sou at the entrance exam day. She decides to apply to the same dormitory as him, but it turns out that the dormitory is founded by a researcher for the residents to fall in love!! Not to mention, anyone who becomes a couple within a year will receive 100 million yen! This is the start of a dormitory-only love game involving six people!
