Quick Transmigration: This Killer Is Beautiful and Kind!

“Falling in love with Ji Yu is only natural”!!!!!! As usual: melodramatic Mary Sue, a bit of a harem, love at first sight, inexplicably falling for you, lightning-fast pacing, all physical chemistry and no emotional commitment. A quick transmigration story, with around 20 chapters in each world. It’s about more than romance: there’s friendship and family, too. The heroine has a complicated personality, but she isn’t a bad person. Might she use one of the male leads from time to time? Might she occasionally date several people at once? Is it all to complete her mission? Or maybe she’ll have a few relationships along the way. The heroine won’t have children. Also, the heroine and the female side characters won’t get into fights over a man, so don’t worry: there won’t be two women fighting over one man. But they will fight over money and status. It’s only natural; people compete with both men and women. There is competition, but it’s only over limited resources. The men will compete for the heroine. A battle royale of rival suitors is a must. The heroine can love whoever she wants, entirely depending on her mood. As she completes her missions, the heroine’s personality will fit her role, but she’s the one in control. It’s all an act, even her helplessness. Everything is for completing the mission. Content warning: the heroine isn’t a virgin, all the men are, and it’s not one-on-one. They’re all adored by everyone... Finally: The author welcomes suggestions. Leave ideas for settings you’d like to see in the comments, and please be civil.
