Konse de Saigo no Koi wo Shiyou

"Hey... Don't leave me behind this time."

Omi is a college student suffering from insomnia due to nightmares of his past life. Exhausted from lack of sleep, he nearly collapses on a train platform only to be saved by a mysterious man named Chihiro. Omi finds himself drawn to Chihiro, who always seems to be looking out for him. But one night, Chihiro's demeanor changes completely...

"I've waited 200 years for you."

That's when Omi realizes the truth... Chihiro is something other than human. This is a reincarnation BL about a young man who remembers his past life and a non-human consumed by a 200-year obsession.
