"A confession of love with your lives on the line…"
A class of 140 students are brought to an Experimental Town, where a being called 1st claims to be they're "tester" and commands them to display true love for the sake of his test. Confessing your love and having it reciprocated means the pair will be able to leave, but failure means death.
