"Unspoken Truths"

As I walked into the cafeteria, the smell of freshly cooked food and the hum of conversation hit me. I scanned the room, my eyes searching for Oslo. I spotted him sitting at our usual table, his eyes fixed on his phone. I made my way over, dropping into the empty chair beside him. "Hey," I said, nudging him with my elbow. Oslo looked up, a hint of a smile on his lips. "Hey, Kacchan." I raised an eyebrow, teasing him. "Vesper, remember? You told me to call you that." Oslo chuckled, his eyes crinkling at the corners. "Oh, right. You're still on that, huh?" I grinned, playfully rolling my eyes. "Of course I am. I'm just waiting for you to start answering to it." Oslo shook his head, laughing. "You're something else, you know that?" The rest of the group started to filter in, the conversation flowing easily as we caught up on each other's day. But I couldn't help but notice that Oslo seemed a bit more distant than usual, his responses a little slower, his laughter a bit more forced. I made a mental note to talk to him later, to try and get to the bottom of whatever was going on. As we finished our lunch and started to pack up, I caught Oslo's eye, trying to convey a message. He raised an eyebrow, a hint of a question in his eyes. I nodded, trying to get him to meet me outside. After we left the cafeteria, I fell into step beside him, my eyes fixed on his profile. "Hey, Vesper," I said, using the name he'd told me to use. Oslo turned to me, a hint of amusement in his eyes. "You're really going to keep calling me that, aren't you?" I grinned, teasing him. "Only if you start answering to it." Oslo chuckled, shaking his head. "You're impossible, Kacchan." We walked in silence for a moment, the tension between us palpable. I knew I had to tread carefully, to try and get him to open up. "So, what's going on?" I asked, my voice low. "You've been acting weird all day." Oslo's expression changed, his eyes clouding over. For a moment, I thought I saw a flash of fear, but it was quickly replaced by a mask of indifference. "Nothing's going on," he said, his voice neutral. I raised an eyebrow, skeptical. "Oslo, I know you. I can tell when something's bothering you. What's going on?" Oslo sighed, his shoulders sagging. "It's just...stuff, Kacchan. I'll deal with it." I frowned, trying to push him for more information. But he just shook his head, his expression closing off. I knew I had to be patient, to wait for the right moment to push him for answers. But I was determined to find out what was really going on with Oslo, no matter what it took.
