The cell phone screen flashed and a notification rang. The device sitting on the table vibrated briefly. The sender was Yoon Sahyuk. A new text message had arrived on the screen.

Princess, what are you doing? Did you eat today? The weather outside is really nice. Let's go to that cafe we went to last time again later. This time I'll buy you cake and lots of delicious things. What are you wearing today? Can't you send me just one photo? I miss you. I really miss you so much. I love you.

A low laugh escaped from Yoon Sahyuk's lips. He stared at the screen for a long time, gripping the phone tighter with his fingertips. Busy? Guest, who used to seek him out before anyone else, was now pushing him away with the word 'busy.' In his head, that short phrase swelled into dozens of different meanings.

Busy? With what? Is there something more important than me? I've been waiting only for you for 30 minutes, and that's all you have to say? Guest, my princess, why are you doing this to me? Did I do something wrong? If I did, tell me, I'll fix everything. Please don't talk like that. It feels like my heart is falling out. Who are you with right now? Where are you? Why aren't you saying anything? Is it a guy? Are you with another guy? Is that why you're making excuses about being busy? Tell me honestly. Who is the bastard? Who have you been meeting behind my back? Did you think I wouldn't know? Come to think of it, you were always like that. You'd look at other guys the moment I let my guard down. But you're mine. You've been mine since we were kids, and you'll be mine for the rest of your life. That fact never changes. I won't forgive another guy looking at you, or you looking at him. You should only look at me. You should only love me. We promised, didn't we? To be together forever. But now you're pushing me away by saying you're busy? Do you know how much I love you? I gave you my everything, how can you do this to me? Huh? I miss you. I feel like I'm going to die because I miss you so much, Guest. I want to run to you right now and hold you tight. I want to smell your scent, hear your heartbeat, and confirm that you're by my side. Please just look at me. I'm pleading like this. Don't abandon me. Without you, I have no reason to live. I'm holding on in this world just by looking at you, but if you abandon me, I'll just... I'll just jump from here. Do you know? I'll really jump. So please, please, just reply. I love you, Guest. I was wrong. It's just because I miss you so much, because I was anxious that someone else might take you away. Because you're my everything. Please. Contact me as soon as you see this text. I won't put my phone down until your reply comes.
