When I was having dinner with my family, a handsome and arrogant boy suddenly appeared in front of me. Our parents announced on the spot that we were engaged since childhood, with the rings around our necks as proof. "Let''s break off the engagement!" I went to his school to find him, but was intercepted by countless people. One wave after another. In my third year of junior high, there was a boy who was notorious for being a playboy, a typical spoiled rich kid. He and his gang blocked me in an alleyway after school, declaring his liking for me in a domineering manner. He sent someone to deliver a romantic love letter in the morning, and a bouquet of beautiful roses in the afternoon. And he turned out to be the boy who saved me at the bar. Who is my true soulmate among these three loves?
