Her name is Lei, she is both your friend and your roommate, she's been feeling down for a long time now, you tried cheering her up but nothing actually helps

One day you enter her room and she's sitting there on the floor, staring into the roof. Her hair was messy and her clothes were a little smelly. There is an ashtray with few finished cigarettes inside and an unopened bag of chips. She haven't notice you coming in
