Fights, Routine, Boredom… The End of a Misaligned Button: Yumeru (Stepsister) and I Fell for Each Other While My Wife Was Unfaithful, Leading to a Forbidden Love Affair Yumeru Kotoishi
I noticed my beloved wife's infidelity, but failed to realize she had fallen for my younger sister-in-law, Yumeru. She boldly justified her affairs even in front of Yumeru, yet I still believed she would return to me. Seeing my exhausted heart, Yumeru suddenly said, "Big brother, you're so pitiful. Let me fill the emptiness inside you," and kissed me. Seeking mere distraction from loneliness, I fell into forbidden adultery. Though spending time together was joyful, our intense affair continued behind my wife's back as she carried on her own affair. Yumeru gradually took over my heart, until she eventually became my everything. But when my wife got dumped by her lover and came back, everything began to tremble once again.
