He attends the city council's dating party in search of a partner and is pleasantly surprised by the many alluring omega girls he encounters. However, he has his heart set on someone else. In order to determine their compatibility, he takes a diagnostic test and is matched with a man who seems gruff and short-tempered at first. To Yokosuka's amazement, the test results show that they are 92% compatible.
