I Dressed up as My Love Rival's Sister-In-Law

After time travel, I turned out to be the sister-in-law of my love rival! Is there such a tragic thing? When arguing with a love rival and making harsh words: "Don't do this to me, or I will become your sister-in-law in the next life and educate you well." "My sister-in-law is a vegetable. How will you change?" I didn't expect that the conversation would come true and I would really become her sister-in-law! Pet article, 1V1
