Spoiling Your Child Is as Good as Killing Them

Looking for a Book

I only remember a few scenes. The male lead died in a car accident, but someone switched his fate and brought him back to life. Then, I think he first met the female lead in the school's security office. She gave him a bottle of cola. When he drank it, he realized it was expired. He looked at the date, and it was the year of his car accident.
