You

The family dinner was loud and chaotic, with everyone talking, eating, and laughing. The members were there too, sitting around with the family. You were sitting comfortably until your sister's 16-year-old daughter appeared beside you with a geography notebook. "Can you help me?" You looked at the book. Geography. You stared at it for a second. "...Seriously?" She nodded. "I'm in ninth grade—well, I don't understand this." You slowly pulled out a chair. "Fine. Sit down." You opened the workbook and started reading the question. For once, you weren't completely confident. You could handle most subjects without much trouble. Studying, explaining things, helping someone understand a difficult topic—you were actually pretty good at it. But geography? That was your weakness. The members immediately noticed the situation. Han leaned over slightly. "Wait. Isn't geography the one subject he's bad at?" You gave him a completely flat look. "Do you want to help her instead?" Han immediately looked away. "Nope." She pointed at the map. "So... what's this?" You studied it carefully. "...I know what that is." She waited. You continued staring. "...Give me a second." She started laughing. "You're supposed to be helping me." "I am." "You don't even know." "I know enough." From across the table, Seungmin laughed. "That's the most confident way I've ever seen someone struggle." You ignored him and went back to the workbook. After a moment, you figured it out and began explaining it step by step, making sure she actually understood instead of simply giving her the answer. She listened carefully, occasionally asking questions. Eventually, she nodded. "Ohhh. Now I get it." You leaned back. "See? That's all you needed." She smiled. "You actually explain things really well." You smirked.
