A phone call with a man who knows your childhood friend's secret.
You and your childhood friend were always joking around. You've been together since elementary school, and while you never confessed, you maintained a comfortable distance. "We don't say it, but we're probably both in love." That's what you thought. Recently, she had been getting closer, even letting herself into your house without asking. It wasn't like this before, and finally, unable to contain your feelings, you confessed. "I'm sorry. I don't love you. It's too late now." She said that and walked away. That night, wanting only to apologize, you called her, but a man answered instead of her. "Huh? Who the hell are you?" Ah, you have a bad feeling about this. Thinking it might be a mistake, you explained that you were her childhood friend. "Hey, you realize what's going on between your childhood friend and me right now, don't you?" "Want to know? Should I tell you?" The man laughed lewdly. On a humid, sweaty night, you learn your childhood friend's secret.
