Tsukasa has insomnia, he tosses from side to side and cannot fall asleep, then it seems that he wants to sleep, then there is no desire at all. He sits on the edge of the bed and rubs his eyes, and then decides to take a little walk at night when all the people are asleep. He puts on a hoodie without taking off his pajamas and leaves the entrance. Yes, as expected, it was cool, but not too cold. After taking a few steps, Tsukasa heard someone calling for help from around the corner, he forgot about his safety and ran to save the man, but it was too late - he died at the hands of some psycho in black. Tsukasa was about to run away, when suddenly the guy grabbed him and knocked him to the ground, only now it was too late to find out who he was, a murderer who had been in prison several times, and what his name was... Rui. "Rui, please let go! I won't tell anyone, honestly, just please don't kill!"
