**Close your eyes and you will be reborn, open your eyes and your soul will change**
On the eve of his 18th birthday, Su Han received a "death gift":
Every time he fell asleep, his body would be occupied by strange memories.
The expiry date of 2035 is marked on the convenience store shelves, the girl's hairpin flashed at the murder scene, and my sister's stab wound healed automatically at midnight - all the absurdities prove that "he" who slept last night is already dead.
In order to find out the culprit who tampered with his memory, he had to use caffeine to stay alive.
