After Losing His Memory, He Woke up with a Fiancée Next to Him!

After a car accident on a rainy night, a young man woke up with amnesia and found a purple-haired girl in front of the hospital bed who called himself his "fiancee". She was gentle and considerate, but it made him feel uneasy. The tracking records in the diary, the charred corpses in the morgue, the strange text messages in the middle of the night... He moved into an old villa with her, but he encountered time gaps, items that disappeared out of thin air, blood letters and burnt cloth in the basement one after another. The cracks in his memory are getting bigger and bigger, and the truth is hidden behind the illusion - and he probably shouldn't have woken up from the beginning.
