"You're biting your nails again."
Hiyori quietly pointed out. Kaito hurriedly lowered his hand.
"I do it without noticing. I want to stop though."
Sora asked with interest. "Since when have you had this habit?"
"Since elementary school. Before exams, or when I'm nervous, I unconsciously do it."
Hiyori gently began explaining. "That's a habituated behavior. A specific situation becomes a trigger, and it happens automatically."
"Trigger?" Kaito asked.
"A stimulus that serves as a cue," Sora supplemented. "The emotional state of nervousness triggers the behavior of nail biting."
"But why can't I stop even though I want to?"
Hiyori continued explaining. "Habits have strong power. In psychology, there's a concept called the habit loop."
"Habit loop?"
"Three stages: cue, routine, reward." Hiyori drew a diagram in her notebook.
Sora began to understand. "Nervousness is the cue, nail biting is the routine. And the reward is...?"
"Temporary relief," Kaito answered himself. "While I'm biting, I somehow feel calmer."
"Yes. That reward gets stored in the brain, and you repeat the same behavior next time."
Kaito pondered. "Then how can I stop?"
Hiyori said gently. "Completely eliminating a habit is difficult. But you can replace it."
"Replace?"
"Take a different action in response to the same trigger. For example, when nervous, take a deep breath, clench your fists."
Sora added. "The brain rewires the pathway. Overwrite with a new habit."
"Exactly," Hiyori nodded. "This is called habit substitution."
Kaito said anxiously. "But I might forget and go back to the old way."
"That's natural," Hiyori encouraged. "The brain's neural circuits don't change immediately. Repetition is needed."
Sora asked while taking notes. "How long does it take?"
"Research says an average of 66 days. But it varies by individual and habit complexity."
Kaito sighed. "66 days... that's long."
"Building small successes is important," Hiyori said. "If you endure one day, that's progress."
Sora suggested. "How about keeping a record? Put a circle on days you didn't bite your nails."
"Good idea," Hiyori agreed. "Visualization makes it easier to maintain motivation."
Kaito became a bit more positive. "I'll try it."
"One more important thing," Hiyori continued. "Don't blame yourself. Even if you fail, it's part of the learning process."
Sora supplemented. "Perfectionism actually hinders habit change."
Kaito laughed. "True, when I fail, I give up thinking 'it's over.'"
"Reframe it as 'I learned again,'" Hiyori said. "This is called a growth mindset."
Sora wrote in her notebook. "Habits are the brain's efficiency system. So they're hard to change, but not impossible."
"Yes. The brain has plasticity. You can change at any age."
Kaito suddenly asked. "Hiyori-san, do you have a habit you want to stop?"
Hiyori looked a bit surprised. "...I do. I tend to take on others' problems too much."
"That's also a habit?"
"Yes. An unconscious behavioral pattern. To avoid my own anxiety."
Sora said quietly. "Awareness is the first step."
"Exactly," Hiyori smiled. "Without self-awareness, there's no change."
The three sat quietly thinking. A habit you want to stop isn't just a bad habit, but a pattern the brain has learned. So you can relearn a new pattern.
"Let's do our best together from today," Hiyori said.
Kaito and Sora nodded. A small step was the beginning of big change.
