Eyewitnesses in the Self-Study Class

Sunlight filters through the floating chalk dust during a self-study class at No. 3 High School. Beneath the veneer of a peaceful classroom, everyone wears a mask of lies: a missing girl, a locked reading room, and a coordinated alibi—a collective silence covering up a homicide. Lin Yan, a young man gifted with eyes that can pierce through disguises, follows fragments of notes and hidden marks to peel back the layers of a three-year-old bloody case, only to stumble upon a dark chessboard spanning sixteen years. Twist after twist unfolds: the school board director is merely an abandoned pawn, the founding generation of students built an exclusive and secretive circle, the serial murders serve as an artificial trial, and an endless cycle traps every generation of truth-seekers. He is both the creator of the chess game and the sole variable within the cycle. When all the pawns, chess players, and restless souls find themselves trapped, the youth uses his unwavering resolve to cut through destiny. In the end, he discovers that the deepest darkness is never found within the locked rooms of the schoolhouse, but rather in the inextinguishable malice—and the never-abandoned kindness—residing within the human heart.
