"I like being alone."
Leo said while reading a book at a library table. Sora and Kaito sat across from him.
Kaito was surprised. "You don't get lonely?"
"Loneliness and being alone are different," Leo answered.
Sora showed interest. "Psychologically, how are they different?"
Leo closed his book. "Loneliness and solitude are different concepts. Loneliness is an emotion, solitude is a state."
"Emotion and state?" Kaito asked.
"Loneliness is felt when you want connection but can't get it. Solitude is physically being alone."
Sora began to understand. "So you can feel lonely even among many people."
"Exactly," Leo nodded. "Conversely, you might not feel lonely even when alone."
Kaito thought. "I get lonely quickly when alone."
"That's because your social needs are strong," Leo explained. "Humans are social animals. Seeking connection is natural."
Sora asked. "But Leo-san, you like being alone, right?"
"When you choose to be alone, that's freedom," Leo said. "Different from forced isolation."
Kaito tilted his head. "Is that difference important?"
"Very important," Leo emphasized. "There's a psychology theory called self-determination theory. People need autonomy."
Sora supplemented. "Being able to choose for yourself leads to happiness."
"Yes. Choosing to be alone versus being made alone have completely different psychological effects."
Kaito pondered. "I see..."
Leo continued. "Introverts recharge energy during alone time. Extroverts gain energy from being with people."
"I'm extroverted, so I'm bad at being alone," Kaito understood.
Sora asked. "But too much loneliness isn't good either, right?"
"Chronic loneliness becomes a health risk," Leo acknowledged. "Research shows it has dangers comparable to smoking."
Kaito was surprised. "That much?"
"Loneliness increases stress hormones and reduces immune function. Also affects the cardiovascular system."
Sora asked seriously. "Then how should we balance it?"
Leo thought. "Have quality social connections. Quality, not quantity."
"Quality?"
"Relationships based on deep understanding. Psychologically healthier to have a few friends who understand you than a hundred superficial acquaintances."
Kaito asked. "I have many friends, but don't have deep conversations. Is that loneliness?"
"Possibly," Leo said quietly. "Social isolation and emotional isolation differ. Even with people around, you feel lonely if not understood."
Sora wrote in her notebook. "The boundary between loneliness and freedom lies in choice."
"Good summary," Leo acknowledged. "When you choose to be alone, that's freedom. When you have no choice and are alone, that's loneliness."
Kaito said a bit sadly. "But even with choices, sometimes you end up alone."
"That's natural," Leo said. "Relationships change. What's important is having the ability to create connections yourself."
Sora asked. "Ability to create connections?"
"Self-disclosure, empathy, trust building. These are learnable skills."
Kaito became positive. "So I can get better with practice?"
"Of course. Social skills are like muscles. They get stronger when used."
Sora said quietly. "Both time alone and time with people are important."
"Balance," Leo concluded. "Neither complete isolation nor complete dependence is healthy."
Kaito laughed. "That's difficult."
"Because we're human," Leo smiled. "There's no perfect balance. You adjust from time to time."
The three sat quietly. In the library space, together yet each facing their inner selves.
"This might be one kind of balance," Sora said.
Leo and Kaito nodded. The boundary between loneliness and freedom isn't fixed, but constantly moving.
