"Oh no! Why did it have to be the male lead that I slept with?!"
Upon waking up, I found myself transmigrated into a side character in a novel — the Earl's daughter, Repley!
I initially thought I could just quietly enjoy a life of luxury and wait for the novel's ending, assuming everything would wrap up smoothly.
But then, at a party, I got drunk and made a terrible mistake.
After sobering up, I realized I had spent the night with the cold and ruthless male lead!
And now, he insists on marrying me to take responsibility?!
"Since we both gave each other our first time, isn't it only natural to be responsible for one another?"
