The Female Lead Who Flirts with Girls and Guys Every Day

[Major revision of the full story. Feedback is welcome!] The female lead comes with a halo that boosts everyone's affection for her. She's a womanizer, often flirting with girls and guys, intentionally or otherwise. Characters of all kinds fall for her, with everyone harboring ambiguous, one-sided feelings. The female lead remains single throughout and will never fall in love with any character. [She leaves lovers without a backward glance, passes through a thousand gardens without a leaf clinging to her.] She has a huge harem, with rivalry and jealous spats breaking out at any moment. Her ability to smooth things over is maxed out. There is no male lead. The male supporting characters are basically monsters she happens to acquire by breaking their seals in various ways.
