Haneda Mei (Ono Kari) woke up one day and found that she had lost her memory for a year.While losing his memory, he gained unprecedented happiness.With a meaningful job, my gentle fiancé Kanata Nishijima (played by Koike Teppei), and my friend Sui Shinohara (played by Fumika Baba) who died in high school, everything seems to be going smoothly...

“You are a murderer!”

He was called a “murderer” by his colleague Ryunosuke Aizawa (played by Koumi Hyoutou), and a “blood-stained white shirt” was found in the room where he used to live.“What on earth did I do...?” Meiyi couldn't hide her confusion.

Afterwards, when Mei returned home, she showed Nishijima her blood-stained clothes and told her “his wonderful memories”.Then he planned to go to the police station, but was stopped by Nishijima, who took the blood-stained shirt for identification.

The next day, Mei went to work at the company and saw Cui.Because of a certain case, I was responsible for hair and makeup.

Under such circumstances, Mei encountered impossible troubles at work.And, I received a text message that said [Nishijima has a lover]...!?
