Episode 1

The protagonist Mei Haneda (Karashi Ono) was found comatose in the mountains and was sent to the hospital. When she woke up a month later, she found that she had lost a year of memory - she was supposed to be with her friend Rina Nakatani (Nagi Shibuya) after attending the event.Saki fell asleep at home after her birthday party, but now a doctor named Kanata Nishijima (Teppei Koike) who claimed to be her fiancé appeared in front of her.What confuses her even more is that she reunited with her best friend Sui Shinohara (Fumika Baba) who was thought to have died in high school, and found that she had been transferred to her dream job.

Psychiatrist Kyohei Satake (Shibuya Kento) provides Mei with suggestions to restore her memory.In order to find out what she did during the blank year, Mei followed clues from the past and came to a road in the mountains.There, her new colleague Aizawa Ryunosuke (Hyutou Kokai) told her: “You are a murderer...”, which made Mei confused...

According to Ryunosuke, Mei went to the apartment where she used to live and found a white shirt“ stained red with blood”...!“What on earth did I do...!?”Hidden in the lost memory is a “secret” that even Mei herself does not know. What is this secret?Can Mei finally touch the truth...?

Nishijima's every move reminds Mei of her father Jun Haneda (Hagiwara Sage) when he was alive.Mei, who had not been with her family for a long time, felt happy because of Nishijima's existence, and finally decided to hold a wedding, accept Nishijima's proposal and kiss him.

At the same time, Ryunosuke is looking at a photo, which shows Mei, Sui and a young man who looks like a classmate (Shuichiro Naito) from high school, and the three of them are laughing together.Ryunosuke wonders what kind of connection there is between Mei and Cui...

However, Cui was nowhere to be seen at the wedding scene.Just as Mei and Nishijima were about to exchange a vow kiss, the door opened and Sui appeared in a white dress...!Tsui said “congratulations” to Mei, while Nishijima looked at her in surprise.

Later, Tsui apologizes to Mei and points out the place where the two reunited.Eager to learn about her past, Mei came to the mountain, and Ryunosuke once again raised suspicions of murder against her.At this moment, a car horn honked from behind, and an uneasy scene flashed through Mei Yi's mind - someone lying on the ground, bleeding profusely.What the hell is going on...?Ryunosuke asked Mei to check out the room where she used to live, but Nishijima said that Mei had moved away.“Did I lie to Mr. Nishijima...?”

At the same time, Satake and Rina hugged each other intimately on the bed, and Satake secretly sent a message to Cui on his mobile phone: [Everything goes well]

On the other hand, Cui, wearing a long white dress, came to Nishishima's apartment.“Finally it was just the two of us”, Cui walked towards Nishidao with a provocative smile, said “you are mine...”, and then kissed him...!?
