Tsubasa Kumagai leaves behind old grudges and memories, moving to Tokyo to start her life anew. She doesn’t know that her new boss is the very person she has hated and wanted to get revenge on for years. Things at work don’t immediately become smooth. The new assistant begins to get under the skin of the commissioner’s assistant. Kumagai knows how to stand up for herself, which sparks the inspector’s curiosity and feelings about her. Getting the love of a person who lives on revenge is difficult—more than that, it’s impossible. She’s a good worker, but in life everything is more complicated. The search for the “Tokyo maniac” pulls the girl into very complicated adventures, from which she can escape only by sacrificing the most important thing that Kumagai has. What will the heroine choose: to be happy in the past, though with a broken heart and thoughts about another man? Or to change the past, where her enemy will be punished, while she herself runs to the future—where Tsubasa will be waiting for a soulmate who filled her heart with love, replacing revenge.
