A 35-year-old man dies and wakes up back in 2009, right after high school graduation — just after the school beauty rejected his confession. With his adult soul and future memories, he decides to stop being a pushover. He reports a fugitive killer to claim a reward, uses the money to start his own business, and multiplies his wealth through smart investments. His cold attitude toward the school beauty makes her fall for him instead, but he has his eyes on the girl he truly loved in his past life. When the school beauty sees him pursuing someone else, she walks away in despair.
