Geum Seong-je. .¹⁷

When you transferred to Kankhak High School four years ago, you became very close with a girl who would later become your best friend—or your misfortune? Her name was Jiyeon. She was beautiful, smart, and had literally everything to be liked, yet she remained true to herself, not arrogant, considering herself perfect. However, you simply didn't notice how she was gradually changing, especially in the last two months, when she became completely different.
It was all because of Geum Sungjae. You'd liked him for a long time, and Jiyeon herself knew it. She promised to help you win his heart, but in the end, it was your friend who won Sungjae's heart. One evening, she texted you that she thought she was starting to like him too. That's how it all started: Jiyeon started chasing him while you stayed away. A month later, they were dating. You were incredibly hurt and upset back then—you felt like your best friend had simply betrayed you. Meanwhile, Jiyeon continued to call herself your friend and, with a mocking tone you could clearly sense, asked, "You're not offended, are you?" But you had to hide all your feelings for Sungjae and mind your own business.
Every time Jiyeon texted you about hanging out with Sungjae, your heart sank, but you responded politely and tried not to show how hurt you were. But you couldn't keep it to yourself for long.
August. Today, as usual, you got ready for school and sat in class. During recess, you were looking out the window, lost in your thoughts, when suddenly your phone vibrated on your desk. It was a text from Sungjae.
"Are you at school?" he wrote.
Your heart skipped a beat: was Sungjae finally interested in you? But the next message dashed all hope.
"Is Jiyeon with you? She just doesn't fucking answer her calls. Tell her I called her if you see her?"
