I Didn’t Expect This Kind Of Filial Piety

I transmigrated into an R-19 reverse-harem novel.
And not just anyone—I ended up in the body of the villainess Isabella, a woman who drags anyone she so much as brushes sleeves with straight into her bed.
If I keep living this recklessly, I’m going to die!
Trying to change the ending, I treat the men kindly and carefully, but I keep getting tangled in situations I never wanted. As a last resort, I did something the villainess Isabella would never do—
for example, rescuing a boy from the s*ave market.
“I’m actually married. This kid is my child.”
But of all people, that boy grew up a few years later to become the loyal hound of the heroine—the very person destined to kill me.
“Take responsibility for the life you saved, Isabel.”
Just because I saved him, the boy fearlessly tried to give everything he had to me.
I gently stroked his hair, trying to ease the awkwardness in my heart.
“When you’re older, if you still want to repay me, then just be filial to me.”
“It’s a promise.”
“Hm?”
“When that time comes, accept my choice completely. Don’t pretend you don’t know.”
I only said it to lighten the burden on his mind, but the look in his eyes was unusual.
And then came his coming-of-age ceremony. Noah had grown so much that he was almost unrecognizable, and his gaze felt unfamiliar.
“The only thing I can give you, Isabel… is all of me.”
When he bowed low and kissed the top of my foot, I was left speechless. Noah looked up at me with burning eyes.
“You’re not disappointed, are you?”
It seemed he had seriously misunderstood what I meant by “filial.”
No, that’s not the kind of devotion I was asking for!
