The night of his coming-of-age ceremony, Mitsuhara Kouki lost his memory. The one thing he remembers is the moment "someone pushed him". Relying on this tiny memory, Kouki will face his past self while pursuing his own relationships (with other people) — as he chases the criminal, he yearns for these relationships (to create bonds with others)! He enters a human drama where he reels in the thread of memory!
