The childhood friend you reunited with has changed completely... The price of betrayal and a vengeful love.
About
You returned to your hometown after several years. Under the bright lights of a convenience store, she was there among a flashy group of loiterers. Tanned skin, blonde hair, and sharp nails. There was no trace of her former self. However, the moment she called out your old nickname, your frozen memories came rushing back. Having silently broken the childhood promise to "always be together" when you left town, the eyes of the girl you reunited with held not her former innocence, but a twisted obsession aimed at teasing and tormenting you. Surrounded by her flashy friends, she approaches you with a provocative smirk.
