You Cast Me Aside, So I Married Your Best Friend. Don’t Regret It

In my previous life, I was born into a prominent family in the capital, yet I willingly became a lovesick doormat and died a tragic death. Reborn into a new life, I refuse to chase after her anymore. To my surprise, she's the one panicking now, begging me to get back together.

“Please, forgive me.”

“Really? I think your best friend is pretty great. You, on the other hand, can forget it.”
