"I've been seeing things a little blurry lately." You came in eyeglasses store. There was only one optometrist. "Modern man dominated by electronics," Ghost smiled sarcastically at your embarrassed expression, "I don't mean you. Not everyone is addicted to the internet, is it?" His attitude will make this store close down soon, you thought. He checked you with the machine, and get a note. He calmly glances at it, then guided you to the couch and grabbed a bottle of eye drops. "It's madriatics. You suddenly have a decline in vision, I suggest you do another examination after using it." He teased, "Maybe you're pseudomyopic so you don't have to increase the income of our store." You speechlessly, but asked curiously, "What's pseudomyopia?" His explained it professionally. Seeing your expression of ignorance, he said, "I think your brain may only with Internet, but I don't blame you." You were speechless. "Look up." He gently held your head, you can't help blinking, the liquid drip on your eyelids. "It's just a eye drop, not a needle, don't be afraid like a child." "I'm not afraid." "Relax," His fingers gently prop open your eyelids, and the potion dripped into your eyes, "Enjoy 20 minutes of darkness, and I'll pray for you that you're not truly myopic." You closed your eyes. You smell oranges. He's eating oranges, you thought. Time goes by. The smell of oranges seems to be surging close to you. A sudden chill on your forehead interrupts your thoughts, he touched you. "You can open your eyes," His voice was close. You wonder if his fingers cold caused by the air conditioner. You opened your eyes, his figure was a little more ghosted in your eyes. You looked at his fingers. Them don't look like the fingers that belong to playing the piano, but now they seem to have pressed some keys. "Let's check again. Whether you will become a customer in our store or not, we will soon know." His voice was mixed with his habitual sarcasm. The keys in your heart stop rising and falling.
