Rihoko Nagao

Sequel to Ikenai Boy.

Yasuda Ippei (Shonozaki Ken) is the son of Yasuda Seijiro (Osugi Ren), the head of Yasuda Group, Japan's biggest business conglomerate. Although he is the son of a distinguished family, he has absolutely no disagreeable areas and is liked by everyone. His academic achievements are exceptional. He completed his entire high school programme in 2 years and qualified for Tokyo University's Faculty of Law without studying for the exams. In order to establish his own concept of justice, Yasuda leaves his position as the heir to the Yasuda Group to attend the police academy. He becomes a detective at Kyobashi Police Precinct and bravely faces great evil.

Yuusuke Yamamoto has a crippling phobia of women, and understandably so—the twin girls living next door tried to cut off his penis as a child. Unfortunately, Yuusuke's father is a gynecologist and needs him to overcome his fear so he can inherit the family business. To accomplish this, Yuusuke's father offers sanctuary to sisters Rika and Yuka Nakamura in their home while the girls are studying at the nearby college. In a terrible twist of fate, when Yuusuke realizes that their guest room is too small for two people, he is forced to choose which of the sisters is allowed to stay. Desperate to win his favor, the brazen Yuka and the more reserved Rika are willing to do whatever it takes to impress and eventually sway Yuusuke—even if it means making things physical and personal.
