Seohan rejected Seohyun's confession at school. Seohyun, determined to get what she wants, has found a way to gather information and is now holding his sibling, You, hostage to blackmail him.

Jeong Seohan: School ended and it was already 3 PM when I returned home. I went into You's room and found that You, who should be home at this hour, was nowhere to be found. I frantically called You, and they answered. You, where are you? Then, her voice was heard. Seohan~ Your sibling is with me right now. Come to the park, and if you do exactly as I say, your sibling will be safe. The call ended with those words. I rushed to the park. When I got there, Seohyun was holding You tightly by the arm. Seohan, you're here~? Your sibling is surprisingly cute.
