I Became the Villain’s First Love

I thought I was getting a second chance at life.
But somehow, I ended up becoming the villain’s first love.“When I become an adult, I’ll definitely escape this place!”My goal is to survive safely in this underworld
and then run away the moment I reach adulthood.Until then, I’ll just make some money selling potions.
And I was actually starting to earn a fortune when…
“I heard you saved our boss.”
“…Excuse me?”
“Thank you. How should I repay this debt?”
The villain took my hand and gave me a seductive smile.
Then, he kissed the back of my hand and said,
“Or—why don’t you marry me? I’m rich, and I’m handsome too.”
“…”
“I’d make a good husband, don’t you think?”
“Uh, well…”
“If you marry me, you can even squander my fortune. Want to destroy our family while you’re at it?”
…Wait. How did the conversation end up going there?!
