It was a story passed down from one generation to another in Japan. The tale of two strangers from different nations whose relationship blossomed into something that not even destiny could handle. Denki was just walking through the library shelves of UA High School when a book caught his attention. The title read: For Once, Love Was Beautiful. Written by none other than Kenjiro, his paternal side's maternal great-grandfather. It's not everyday that he's interested in historical romance books, so he took it with him and started reading. Upon flipping the first page, a note was written. "There is more to life than what you ever expected, and of those uncanny things to encounter is a love that would be remembered forever because of its pure sincerity and passion."
