The Assassin's Darling: The Sickly-Sweet Young Lady Is a Little Too Adorable

Modern designer Su Wan unexpectedly transmigrates into the body of a sickly, pampered legitimate daughter of a general's household. The original owner fell ill with depression after her parents forced her to marry a young nobleman she didn't love. She binds herself to the Matchmaking Ledger System and must earn Matchmaking Points by completing good deeds, such as finding a match for a maid or resolving disputes among commoners. She can then spend them on prize draws for handy items like the “Heart-Soothing Flower,” which calms emotions, and the “Silver-Tongued Pill,” which dispels awkwardness. To escape her parents' control, she becomes entangled by chance in a mission for the shadowy organization Shadow and repeatedly crosses paths with Xie Yan, a cold-blooded assassin. They go from testing each other to secretly falling in love, but Xie Yan's hidden identity as a “remnant of the regicide” and Su Wan's father’s plan to “wipe out the martial world” plunge them into a tragic romance divided between good and evil. Su Wan pretends to be mad and foolish to resist the arranged marriage and protect Xie Yan, while Xie Yan is willing to expose his weaknesses to keep her safe. With the System's help, they ultimately expose her parents' scheme to “consolidate their power through marriage alliances” and join hands to break free of fate's shackles.
