She and her rival Watanuki clan have never been able to settle their turf war, and they have been on a parallel track. Then one day, in order to really pit the two gangs against each other, she decides to play a certain game with Nayuta, a childhood friend and incoming head of the Watanuki clan. It is a "honey trap game" in which the one who makes the other fall in love with him and make him say, "I'm so happy," wins. The story depicts how the stiff and serious Benio is swept away by the sweet words and actions of the aloof Nayuta. 代々争い続ける常森組と綿貫組。次世代代表として、紅緒と那由多はハニトラ対決（＆同居）することに。 真面目な紅緒はあの手この手でメロメロ作戦を決行するが、那由多にときめかされてしまう！ でも実は、那由多は昔から紅緒に片思い中で…!?
