Minamoto-kun Monogatari

Because of this, Terumi's middle school years were beset by bullying, spearheaded by the most popular and beautiful girl at the time, Chuujou Tsukasa, as an act of jealousy.

The long term consequence of this also resulted in Terumi never getting intimate with women during his high school years, finding even the act of talking with a woman awkward and painful.

Just as he enters Shiun University and makes a promise to himself to overcome the trauma of his past, his father remarries and asks him to move out of the house.

When he arrives at her apartment, she drags him into a special project in which he must seduce fourteen different women in the same fashion of the protagonist of The Tale of Genji.

Subsequent events, such as competing in a beauty pageant against one another, only increases these feelings, with Tsukasa eventually admitting to herself that Terumi has grown strong since their middle school days.

Labeled as "Targets" by Kaoruko, each one of them share some similarities with one of the women seduced by Hikaru Genji, and she instructs Terumi to get into relationships with them, for the sake of her research.
