nexus (n.): a connection or series of connections linking two or more things.
set in a residential building turned prison, where students are trapped in a brutal game of mafia that twists friends into suspects and allies into enemies, paranoia poisons every word and survival depends on who you trust. in the chaos, one boy, go kyungjun, carries a presence that unsettles without a sound, and one girl, used to life on the edges, finds herself drawn toward him. their bond becomes a nexus-an unlikely connection at the center of a world built on lies.
