The Villainess Refuses to Be a Foil, and the Reserved Officer Spoils Her

[Transmigrate into a book + period setting + military marriage + contrasting couple + comeback + villainess + face-slapping] When Su Wan opened her eyes, she'd transmigrated into a novel she'd read called The 358 Tales of an Eighties Contrasting Couple. The heroine was wonderful in every way, while the supporting character who shared Su Wan's name was awful at everything. And to make matters worse, she'd become that doomed supporting character herself. To change her fate, she overturned everything and started over, only to discover that some things seemed to have changed without her even realizing it. For instance, she was supposedly destined to marry someone. Those two people had clearly been worlds apart, so why were they...? And the original heroine, who should have had everything go smoothly, suddenly lost her good name and became the target of everyone's ridicule? All she wanted was to escape her original fate. That was all! The officer: “Honey, we're already married. You don't mind having a baby with me, do you?” Su Wan: “I've got legs, so it'd be a waste not to run!”
