My Boyfriend Announced His Marriage to a Flirt. For Revenge, I Decided to Seduce His Cousin

Day one after the breakup.

My boyfriend posted a photo with his mistress on Instagram, announcing their engagement.

Everyone in our group chat went crazy, tagging me repeatedly.

I silently added my ex-boyfriend's cousin to the group and explained, "Let me introduce you to my real boyfriend."

My boyfriend wanted to sleep with me, but after I refused, he immediately found a so-called true love and got engaged.

He happily posted a photo with his new girlfriend on Instagram: "I'm getting married."

The picture showed their intertwined hands and a large bouquet of roses.
