Young forever

Kim Y/N is in the 10th grade. She has best friends Rosé,Jisoo,and Lisa. They've been best friends since in diapers. But... They all have problems. One day they separated from each other.. but they each met someone with the same situation as them. Ever since they separated Lisa's been stealing from stores, people, and houses. Jisoo has been locked up in a hospital due to her anger issues that she has. They sometimes drug her up to calm her down but she takes more than what she needs. Rosé is always trying to drown herself. In a tub. And as for Y/N? Well ever since the girls left her she's been going up on top of buildings and almost falls down the tall buildings. Wanting to get out of life. Escape it. Now there's only one question. Who will save them all?...
