Flirtatious heroine + sweet romance + heroine who refuses to follow the rules + the male lead is always the same person
After Xia Lian's suicide attempt fails, she inexplicably gets bound to a System and learns that failing her missions ten million times will get her erased. So she deliberately keeps ruining them, until she finally reaches the last world. But then the System tells her she can't see the mission details and will have to figure them out on her own. What is she supposed to do? Ruin her character, of course! The princess doesn't want to marry? She'll get married right away, this very moment! The princess likes strong, handsome men? Then she'll marry that sickly, delicate general! The princess has a bad temper? She'll instantly turn into a gentle, lovable angel! The princess... Is there no end to this? But how did she end up completing the mission successfully? All she wants is to be erased and reincarnated, so why is it so hard? The newly appointed “shady” System trembles like a leaf. “Host, let's talk this out. Do you even know what ‘erasure’ means?”
Much later, a certain big shot in the System world sends wedding invitations to every System. On the wedding night, the big shot doesn't even make it onto the bed, and insists with a stony face, “I wasn't wrong, Lu'er... Chenchen... Lian'er, I was wrong.”
“Get lost.”
