Quick Transmigration: How I Became the Female Lead's Love Interest

I'm 9414, a specialist in the acting department. My mission is to romance the female protagonists... all of them. I fought my former best friend, a womanizing jerk, over his busty wife. In a harem-intrigue story, I promised the Mary Sue heroine, who was my stepmother, that I'd love only her for a lifetime. I flirted up a storm with the cheat-enabled heroine of a rebirth-in-the-entertainment-industry story. After becoming the husband of an ambitious empress, I loved and fought with her in equal measure. My lovesick, corrupted heroine from a cultivation story, off her medication again, crouched on the roof beam watching me all night. A male-female romance. Although the protagonist is a man, the real focus is on the heroines. XD The protagonist is male, with an irresistibly sweet and warm personality. Giving the heroines I regretted losing back then a happy ending. They were already so dazzling. They shouldn't have to settle.
