After Lightning Struck, We Both Awakened

After getting struck by lightning, my childhood friend and I both awakened to the truth. He was the obsessive second male lead. I was the vicious female villain. Neither of us was exactly a good person. In the original story, after failing to win the heroine's love, he set out to destroy the male lead. And after failing to win the hero, I made the heroine's life miserable. Once we woke up to the truth, though, we were both exhausted. So we decided to stop chasing the leads and just date each other instead. The night we got engaged, the cold, aloof male lead and the sweet, innocent heroine both lost it. With red-rimmed eyes, they demanded to know why.
