Having Had My Bride Stolen, I Just Want to Live Peacefully

On the day of the wedding, a stranger broke in. He came to steal my fiance. He starts proposing to her with a toy ring. Ha? He promised to marry each other when they were young. And I was flustered without a moment’s hesitation. My fiancee’s sister appeared in front of me exhausted from being robbed of my bride after being broken off in front of many people. And she comes to my house every day to comfort me… Before I knew it, I found myself doted on and started a happy newlywed(?) life.
