For years, Suzune Horikita dedicated her life to hunting down the mysterious mastermind of the underworld-the man believed to be responsible for countless murders, disappearances, and conspiracies. When she finally succeeds in infiltrating his headquarters, she expects only one thing; Death. Instead, the man she has spent years pursuing calmly places classified files before her,-files that threaten to destroy everything she has ever believed. What if the criminals aren't the real villains? ... What if justice itself is built upon lies? Offered a place by the very enemy she swore to destroy, Horikita is forced into a deadly game of manipulation, deception, and impossible choices. In a world where truth and lies are indistinguishable, the greatest danger isn't losing your life-- It's discovering the Truth.

Ayanokoji Kiyotaka sees his small world inexplicably crumble as flames spread throughout the White Room. The flames crackled fiercely against the imposing white walls that had surrounded him since his birth. Ironically, the flames that engulfed everything around him are the same flames that ignited his heart with a range of new possibilities. He is given a new chance to rediscover and become the best version of himself.

What happens when the perfect weapon of the White Room is finally forced to become human-by a girl who was never afraid to be brave? Can a man built on control, survival, and emotional emptiness truly learn love, or will it consume everything he was designed to be? And what if that love doesn't just change him-but rewrites the fate of everyone around him, from former classmates to rival geniuses, turning a world of manipulation into one of fragile, chaotic warmth? When Suzune Horikita steps into Kiyotaka Ayanokoji's life, does she save him... or become the one thing even he can't control?

In this story, Ayanokoji is a delinquent who does whatever the hell he wants. (He'll manipulate, scheme, and even seduce if he deems it necessary. He truly doesn't give a fuck.)

The White Room is gone. Atsuomi is behind bars. And at fourteen years old, Kiyotaka is adopted by Chairman Sakayanagi... becoming Sakayanagi Kiyotaka. Guided (and constantly teased) by his new sister Arisu, Kiyotaka spends a year learning how to live in the real world before stepping onto campus at Hibiya High School. Between chess matches by the fireplace, awkward café orders, and organic high school encounters, the masterpiece of the White Room is about to find out what an "ordinary life" actually feels like.
