My Atypical Marriage

I thought I met love, but it was just a silent competition with a substitute. Because of jealousy, he seduced his cousin to seduce his best friend's boyfriend. After he died, one got his child but refused to get married all his life; the other got his love but married a man he didn't love. In order to see you every day, I married your best friend. I am always comparing myself with her shadow, but there is a thorn in my heart that cannot be removed. It is bloody, a little painful, and a little itchy.
