Time Travel Back to 2007, I Want to Develop Social Cow Syndrome

Once I traveled through time, I found my younger self in a parallel world, and I lurked beside her for decades with my skills. I only have two purposes for coming here. One is to cultivate her into a bull syndrome, and the other is to prevent her from marrying my current husband, Su Jin. I never thought that my husband Su Jin also traveled here. He said that her purpose was to make the other him in this world marry the other me in this world! Well... Let's just wait and see! It's not yet certain who will win and who will lose!
