Y/n was walking around the streets to take a breath and to relax when she found a group of detectives surrounding something. She walked near to peek on what's going on as she removed one side of her earphones to listen to them but one of them noticed her. "Hey, what are you doing? This is a crime place." He told her. "C-crime place," she asked, fear filling her body. Her home is just around the corner and there was a crime going on? "Yeah, she was killed yesterday. Didn't you watch the news channel?

Y/n got ready for her work and stopped by a nearby convenience store to buy something to eat. She took a cup of noodles and a kimchi pack and went to the counter to pay for them. After paying, she went to the seats to eat those foods as she listened to her sad playlist again. She didn't recognize the cashier but he sure did recognize her at a first glance. Minho just observed the girl eating from the counter, he also noticed her listening to sad songs just like she did yesterday. Y/n felt someone was watching her so she just finished her food soon and disposed off the packages and walked away from the st
