Simon has always been the type of guy who would calculate before attempting anything. He was kinda like a Living Computer. Things went well in his life as he was going through high school, but one day he found himself transported to an unknown library.

If that was all, he wouldn't be so confused, but as he was walking around, he also found his best friend had been transported here as well, only... HE was now a SHE. This is a story of companionship as these two young Immortals are thrust into an Isekai.
