After a terrible car accident that caused her best friend's death , Yoon Lacy (a 17 years old girl) hasn't spoken a word. The police has closed the case saying it was just a tragic accident, however after the entry of a new student in Lacy's highschool everything changes. Was it truly an accident or was it a planned cover up?

The town had long whispered about the old mansion on Hollow Hill-an ancient, crumbling house shrouded in shadow and mystery. No one had dared enter for decades. Strange noises, flickering lights in the dead of night, and shadows moving behind cracked windows made it a place of nightmares. But tonight, a group of seven friends-Doah, Mako, Yuri, Hannah, Yeye, Isa, and Lacy-were drawn to the house by a mix of curiosity and dare. They laughed nervously as they approached, their breath visible in the cold night air.

In the year 2035, a girl goes to a vintage shop and finds an old phone which she finds really cute and buys. After she gets home, she starts scrolling on it, checking the gallery to find old pictures of what looks like a big friendgroup, while she's scrolling, her vision gets blurry and suddenly faints. When she wakes up, she finds herself in the middle of a random street, as she stands up, she finds a group of teenagers looking at her confused. After a while they decided to let her join the friendgroup. The girl slowly realizes that they're the same people she saw pictures of on the vintage phone.
