Avant-Garde
"Hi honey, how was your day?"
Kagome smiled, kissing Miroku. "Fine. How was work?"
"Tiring. I'm ready for some steamy sex."
She giggled. "After dinner—"
Miroku's cell rang. He checked the Caller-ID: "Sango."
"Oh, okay, go have fun," Kagome said cheerfully.
"See you later!" He kissed her goodbye.
Most couples break up for infidelity.
Miroku and Kagome stayed together so they could cheat. Inuyasha and Sango were first in their lives, but both were married to others. Miroku and Kagome lived their lives waiting for a call from their loves.
Unconventional, yet the happiest couple in the apartment complex.
AN disclaimer: kids, cheating is bad. Do not try this in real life.
