[One heroine, multiple love interests, coercive love, jealousy-fueled confrontations, no decent male leads, an easily wooed heroine, no System, no transmigration or rebirth, pseudo-historical setting]
Heroine: Cool and kind, strong-willed and decisive, brilliant, and beautiful as a mountain spirit or a celestial maiden among the clouds. She is hopelessly dense about romance, easy to win over, and an orphan whose origins are shrouded in mystery.
The male leads and supporting men come in every variety, most of them two-faced: domineering, addicted to secret affairs, scheming, obsessively possessive and twisted, or sweet on the outside and dark within.
Happy ending. All the main characters are adults, and none of them are biological siblings.
[Best enjoyed with cultural logic left at the door.]
