Wei Hang had always had a secret crush on his tutor Gu Weiwei. Five years ago, after a car accident was reported, he thought she had long since passed away. Until one day, he unexpectedly discovered Gu Weiwei at his uncle's home, only to find that she had long become a vegetative state patient, being cared for by his uncle all along. However, he noticed that every night, his uncle would enter Gu Weiwei's room alone, acting very suspiciously. To find out the truth, Wei Hang secretly installed a miniature camera in Gu Weiwei's room, wanting to peek at his uncle's true actions late at night.
