You are an irreplaceable part of me

Kang Si An bites his fingers. He's nervous and restless. He has taken a quick bath, combed his hair, and worn clean clothes. He has done his best to clean the house in a short amount of time. He looks into his refrigerator. There are only frozen foods and bottles of beer. He curses madly. He should have brought something. What can he cook for her? He checks if he has some coffee. He should order food that Kyuri likes. He wonders if it will be delivered on time. He should order it anyway. In case, she decides to go out, where he should take her? He checks the list of restaurants.

The doorbell rings. He jumps and drops his phone. He doesn't look at the broken screen of his phone. He runs to the door and opens it. He is dazed when he sees her. She is wearing the same clothes that she wore yesterday. Her face is slightly pale. There is no smile on her face.

He lifts his hand to reach out to her, but his hand stops midway. Her yesterday's words echo in his head.
