I loved a rom-com manga, but my favorite heroine was a sub-heroine who would never end up with the main character. One day, I was hit by a truck and woke up as the main character's best friend in that very manga. At first, I thought it was a dream, but I soon realized I had been reincarnated. I found myself alone in a classroom with my favorite heroine, and I confessed my love. To my surprise, I didn't wake up from the dream. I'm determined to make this kuudere heroine happy in this new life.
