Sinful Bonds: The Seduction System Son-in-Law

Rikutu married a woman who loved me when no one else did.

But a month after their marriage… I transmigrated into his body.



Aya, my gentle wife, isn’t the most beautiful — but she gave me warmth when the world turned cold.

I should have cherished her from the beginning.

So when the Seduction System awakened in my mind, I made a vow:



> "Before I conquer the world of women… I’ll make her the goddess she deserves to be."







From that day, Aya's body and beauty began evolving — her loyalty was rewarded.

But fate is twisted.



Her mother? Voluptuous. Lonely. Curious.

Her younger sister? Playful. Teasing. Dangerously bold.



And they all live too close.



The more I control myself…

The more they fall into temptation.



Guided by a system that rewards pleasure, power, and sin,

I must navigate love, lust, and loyalty in a house full of forbidden desires.



> In this game of hearts and bodies,

how far will I go before Aya finds out what kind of man I’ve become?
