Sunlight glistening on sweat, a refreshing smile. Back in middle school, while staying late for remedial classes, the image that always stayed with me was of that girl chatting happily with her friends in the hallway. She wasn't some school idol—she was tomboyish, positive, and kind to everyone. Even to shy me, she'd occasionally say hello or invite me into the conversation, making me feel truly welcomed. I still don't know if that was love. But when I first heard about our reunion after graduation, the face that came to mind immediately was hers. What is she doing now, I wondered. Maybe she's even married. Carrying these anxious thoughts, I attended the reunion. Seeing her smile again after more than ten years warmed my heart. I was genuinely happy to see her once more. But that night, a drunken man started spouting insults. He joked, "Hey, I heard Sena's working as a hostess now." What!? Is she really a hostess? Or maybe even in the sex industry? If that rumor's true, there must be some deep reason behind it. To treat something like that as a joke and hurl insults is unforgivable! Even I, once so timid, reacted under the influence of alcohol, shouting at him, "Senachan would never let an idiot like you touch her!" The room buzzed with tension, but I didn't care—I kept berating him. Later, I approached her and spoke from the heart: "If you're going through something tough, I'd like to help however I can. Keep doing your best at work!" She smiled at me so happily. That smile—etched into my memory forever.
