Strategic Lovers manga volume 1 features story and art by Sanshokuamido.

Kouta Higashiyama’s father is the enormously wealthy founder of a corporate behemoth—but his mother was the man’s twenty-third mistress! He thought the issue of succession and inheritance had nothing to do with him. And it didn’t—until he was suddenly kidnapped as a candidate to be the next chairman, and dropped in front of five beautiful girls, all of whom are in contention to become his lover… But is his whole life really all about choosing whatever and whoever he wants? Or will Kouta himself be the one to be chosen…?
