A group of friends trapped in debt games where the only rule is don't doubt each other, except doubt is the only way to survive. The premise hijacks everything you think you know about loyalty, turns friendship into a weapon they use on each other, and makes you question which betrayal hurts worse, the obvious ones or the ones they convince themselves aren't happening. Read the manga instead.
Yuuichi treasures his friend group above everything else. Life is good, comfortable, predictable. Then a sudden debt appears with their names on it, and they're forced into a brutal game where the only rule matters: trust each other, and you win. Betray, and you lose everything. The catch is simple in theory, impossible in practice. Each round presents scenarios designed to crack friendships from the inside out. Lies become currency. Suspicion spreads like poison. When someone has everything to gain by throwing others under the bus, how do you know who's really on your side? What starts as a confidence exercise becomes psychological warfare. Yuuichi's unwavering faith in his friends gets tested in ways he never imagined. The game knows human nature better than any of them do, and it's designed to exploit every weakness, every insecurity, every hidden resentment that might exist beneath the surface. By the end, only the bonds that survive intact matter. But survival might cost more than friendship ever should.
