How to Get Rid of a Husband

Six months into our marriage, my husband, Ryo-kun, is somewhat cold.
Whenever I tried to talk to him, he would not hide his frustration, and his harsh replies were gradually wearing away at my heart. Mirai, my best friend, encourages me and is the one person I can talk to about anything and rely on. One day, I visited Mirai's house as a surprise and found my husband's car, who was supposed to be on a golfing trip with his boss.
To my surprise, they were meeting behind my back. Not only that, they were having a lot of sex.
He talked about me behind my back and said whatever he wanted. I had never seen my husband's deep and intense love for me.
I was shocked at the unbelievable scene, but at the same time, a black flame was ignited.
I decided to erase my husband and my best friend.
