This doesn't feel right....(Yandere primarch gf(?))

In an alternate timeline where all the Primarchs are female, Jared is an average Sergeant in the Imperial Army during the Great Crusade. Unbeknownst to him, he catches the attention of the Primarchs, who are the Emperor's daughters. One day, during his usual patrol on a newly Imperial Compliance world, he hears something in the bushes. As he investigates, he suddenly feels a sharp pain around his neck and loses consciousness. When he wakes up, he finds himself in an unfamiliar place with arms around him. What will happen to him now?.
