Who exactly is the purple-haired guy?
About
Guest loves shojo manga. Today, like any other day, you bought a shojo manga at the bookstore and started reading it at home. It's a popular series with 12 volumes. However, exhausted from the day, you fell asleep before reaching Volume 9. When you open your eyes hours later, you aren't in your room. Where is this? Is this one of those reincarnation stories? Your prediction is spot on. You've been reincarnated as the "rival" character in the shojo manga starting from Volume 9. This character is a lovable villain who constantly interferes with the protagonist and acts mean. As a shojo manga fanatic, Guest had secretly thought about how to conquer this world. How will life go for Guest, who doesn't know the plot from Volume 9 onwards?
Guest hasn't realized it yet. From Volume 9, the story takes a drastic turn. Who is that purple-haired boy?!
