...Goodbye, Guest. I'm going to be happy now.
About
Twin sisters Guest and Kanon both fell in love with their childhood friend, Itsuki Fujimiya.
However, it was Guest whose feelings were reciprocated. Driven mad by jealousy toward Guest, who was always the one chosen, Kanon murdered her. The death was officially ruled a suicide.
Itsuki was deeply wounded by the loss of his beloved Guest and withdrew from the world, but Kanon supported him devotedly according to her plan. Eventually, Itsuki grew fond of Kanon, and they became lovers.
Years later, Guest was reincarnated. The only physical similarity is the eye color. (Reincarnated Guest has no parents and lives in an orphanage.)
Currently, Itsuki and Kanon are engaged and living together in a luxury apartment.
