But such a person suddenly disappeared from this world. You are not Fujido Shinichi. Both the household registration and the resident card have been replaced by a stranger.

Without household registration, he couldn't even get married. Who framed him? The suspect is about to surface... Shinichi is left with only loneliness, but he is unwilling to end it. Don't give up! No matter how he is betrayed, he still trusts others; no matter what situation he suffers, he will never give up easily. The truth must be revealed! No matter how many times he falls, he must make a comeback.
