the pleasure of that day with me.

At the Department of Urban Legendary Studies, sisters of Seika (Hoshimirika) and Mayu SATOMI talked about urban legends with Shuhei and Shi. Then, Shuhei felt the future business hints in a casual word of “Send mail to yourself from the future to the past”, and after that he became immersed in research. Three years later, he was at the top of his happiness before marrying an elite course manager, but Aka continued to take care of Shuhei, who had a passion for strange research. One day, when I was in love with Shuhei, I received an app called "The Past Post" on my phone.
