Yuusuke Yamamoto suffers from a severe fear of women stemming from a traumatic childhood incident. His father, a gynecologist, requires him to confront this phobia to inherit the family business. To help, Yuusuke's father offers shelter to sisters Rika and Yuka Nakamura while they attend college. When a guest room shortage forces Yuusuke to choose between them, the sisters compete for his attention, willing to go to extreme lengths to win his favor – including increasingly intimate advances. This two-episode anime, 28 minutes each, is a seinen series featuring harem elements, ecchi comedy, and romance.
