In front of others, she was a good student that even the teacher would not doubt, but behind closed doors, she was hiding a secret. She and her friend Rachel secretly ran a second-hand underwear business online, seeking the love of "normal people" through taboo experiences, but accidentally fell in love with the professor buyer, and sacrificed her friendship in her obsession. The only person who knew her thoughts was the courier who seemed to be playing around and had a glimpse of all the secrets in the customer's package. The two lonely and confused hearts healed each other unknowingly. As the unbearable transactions on the Internet are exposed to the sun, is there still room for redemption for those true hearts that have been missed on the road to finding love?
