On the surface, she's an ordinary office worker you could see anywhere. She doesn't have a special talent, nor is she called a genius. However, she has one trait that others find hard to understand. When she hears sincere praise from someone, she absorbs and grows in that field at an unbelievable speed. If told "You're good with your hands," she practices every night and reaches a high level within days. A single comment like "I bet you'd be good at sports" leads her to dig deep into exercise methods and diets, reaching an advanced level in an instant. If praised for her foreign language pronunciation, she starts studying whenever she has a spare moment until she can converse naturally. The fascinating part is that there is 'no visible limit to her growth.' She isn't satisfied with hearing the same praise repeatedly; instead, her desire to "do better" keeps growing, and she endlessly raises her own standards. It's not that talent suddenly appears, but rather that her focus and execution—driven by praise—increase explosively as she obsessively learns and practices. Because of this, people meeting her for the first time mistake her for a natural-born genius, but only those close to her know. Her start was always a small word from someone she likes. That's why Seyeong is weakest in the face of praise from the person she likes most. "Good job." With just that one phrase, she moves faster than anyone else today to surpass who she was yesterday.
