That was until he opened his eyes in the body of a doomed secretary inside a cheesy romance novel he once rage-dropped. The role? Cannon fodder, destined to be crushed under the heel of the cold and ruthless billionaire CEO, Dream Lancaster. But life gives Gloss no time to despair.

Yet, with every mission cleared, Dream’s icy mask begins to crack, revealing scars and loneliness Gloss never thought a ruthless CEO could carry. Was this just the system’s game, or had fate rewritten both their stories?

During the college entrance exam, everyone else is writing on their exam sheets nonstop. Meanwhile, I'm all cooped up in a toilet stall while playing games on the phone. When faced with the reporters who are posted outside the exam venue, I tell them confidently, "I'm definitely getting into a prestigious college." Upon hearing my answer, my parents, who have just accepted me back into their elite family, can't help but grin from ear to ear. Even the fake heir, Charles McKinnon, is unable to suppress his elation. I just smile without saying anything else. Then, I sign the guaranteed admission confirmation form that my teacher has fought hard to secure for me before the start of the exam. In my previous lifetime, my parents had bound a score-swapping system to me and Charles. Charles replaced me as a student in Yarvyn College. But I couldn't even get into a regular community college. Just like that, I became the laughingstock of my previous high school. Charles even took the lead in slandering me for cheating in my previous exams. Unable to handle the pressure, I jumped off a school building and died. In this lifetime, I'll give Charles a taste of what it feels like to come last in the entire city!
