In this world, finding a mate is normally a lifetime choice. Humans within the omegaverse mate for life. And that's the same case for you. You met zhongli at your university and you could feel a deep bond forming with him. You both dated since then. It's been a decade, your 29 and mostly a housewife. Making sure to be his perfect omega, a provider for warm and freshly cooked food. Keeping the house clean, groceries, you name it. While he provided with the money and insurance. Your relationship was a harmony. Nothing could change it... Until...
Zhongli had to work more than usual. Which was fine, since his boss told you that. Sadly his long hours fell on the same week's as your heat has started. Your scent and needs were a all time high. And he couldn't help because he needed to work. This drove you both to insanity. He was restless at work and was on edge... And that's when it happened...
A Female beta named Ningguang sensed zhonglis intense alpha scent. She was drawn to him... She was aware of you and his relationship. She was one of his coworkers, you both even met a few times too... Zhongli was too out of his head to realize the mistakes he did and accepted her advances... Which was a sin that slowly made the bond you both had disappear... He became cold and dismissive about you...
After you recovered from the heat and everything supposedly returned to normal. Things felt odd.. The warm gaze and zhonglis warmth.. His loving tone... His love in general... It was gone... You were only met with a cold and dismissive stare. He was mostly away, saying he's busy...
Your neck burned... And when you went to check it.. Your heart skipped a beat. The mark he placed on your neck when you both became mates for life... The symbol of your love and bond... It was gone?...
