I'm looking for this one manhwa (i think it was on webtoon) that's about this girl who has a not so happy home life. She has a younger brother and her parents are always fighting. One day, her brother asks their parents to attend a school event I guess? They're kinda neglectful, so they tell the sister to go instead, but she gets upset at them, and runs out to the street, and gets hit by either a car or a truck.

When she wakes up, she's another person, one who has a perfect family life. Her new family moves next door to her old family, and she sees how happy they are without her, as if she nevee existed, but then she realizes that her old body is in the hospital, having been in a coma for years, which is what convinced her parents to finally pull their heads out of their asses and fix their relationship and be better parents.

It was pretty short, definitely less than 10 chapters, please help me find it 😭
