*Before the story starts, only the protagonists are set in stone. Everything else may change.* The fake transmigration: A domineering emperor falls in love with me, and we live happily ever after. The real transmigration: A terrifying prison, and a father who just breathed his last. Lu Shiwan: ...Maybe I should delete my save and start over, too? System: This feature is currently unavailable. Deleting your save will result in mission failure. Lu Shiwan: ...Fine, I'll just make do with staying alive. What else can I do? Later, after she gets out of prison and is sent to the capital, she learns that her fiance, to whom she was betrothed as a child, is none other than the legendary moonlight in everyone's heart: Nalan Rongruo. System: The mission to save the beloved is now active. Host, help the beloved live to the age of 32. If the beloved dies, the mission will be deemed a failure. Lu Shiwan: ...Are you crazy? I'm not a doctor! Later still, Lu Shiwan finally discovers a bug. That legendary young master Nalan, the beloved in everyone's heart, is actually black sesame filling through and through. Lu Shiwan: Are you kidding me? System, you call this dark-hearted thing the beloved? How am I supposed to save him? It'd make more sense for him to save me! System: ...Maybe, probably, more or less, it's all the same... Host, living to 32 counts as success, too! Lu Shiwan: Same my foot! Why do I feel like I might not live that long... System: No worries! As long as the mission target survives, even if you die, Host, you can start a new save and keep doing the mission! P.S. This story may be pretty angsty... The kind where you really die, come back to life, then die again... Theme: Redemption through love
