Synopsis
Yuusuke Yamamoto suffers from a severe fear of women, a condition born from a traumatic childhood incident where the twin girls next door attempted to mutilate him. His father, a gynecologist, hopes Yuusuke will eventually take over the practice, so he must conquer this phobia. To help, Yuusuke's father allows sisters Rika and Yuka Nakamura to live with them while they attend a nearby college. When Yuusuke realizes the guest room is too cramped for both girls, he is forced to decide which one can remain. Eager to secure his favor, the bold Yuka and the more reserved Rika resort to any means necessary to impress him, even if it involves getting intimately physical.
