"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.

Note: Originally serialized digitally through Jump+. Only the first three collections were published physically and all later releases were digital exclusives.

Haiba Sumio is a student at a Tokyo High School with an interesting ability... He occasionally falls asleep and wakes up with premonitions of the future written out on his "Dream Diary". With this ability, Sumio helps out people in trouble before anything bad happens, until one day when his peaceful life completely changes.
