"Read this."
Aoi showed Yuki a message. Short and efficient text.
"It's clear," Yuki answered.
"But something feels missing."
Riku looked over. "True. It feels cold."
Aoi was puzzled. "But it has all the logically necessary information."
"That might be the problem," Yuki said gently.
Mira wrote in her notebook. "Over-compressed"
"Too much compression?"
"Yes. There's lossless and lossy compression," Aoi began explaining.
"Lossless can be completely restored. Lossy loses information."
"For example?" Riku asked.
"ZIP is lossless. JPEG is lossy."
Yuki understood. "But human communication?"
"We unconsciously compress," Aoi answered.
"Extract logical content and remove extra words. But something might be lost."
Mira added. "Emotional nuance is lost"
"Emotional nuance is lost."
Riku reread Aoi's message. "True, just facts without emotion."
"But it's efficient, right?" Aoi argued.
"Too efficient."
Yuki gave another example. "For instance, just 'OK' versus 'Got it! Thanks' feels warmer."
"But information content is the same," Aoi pointed out.
"Information-theoretically the same, but emotion transmission differs."
Aoi pondered. "So even lossless compression loses something?"
"No," Mira wrote. "It's lossy for emotions"
"For emotions it becomes lossy compression."
Yuki explained. "Logical content is preserved, but emotional content disappears in compression."
"So moderate redundancy is needed," Riku understood.
Aoi reflected. "I've overemphasized efficiency."
"Over-encoded kindness."
"Over-encoded?"
Yuki said gently, "In the process of converting emotion to logic, something was lost."
"Rate-distortion theory," Aoi realized.
"Rate-distortion?"
"Trade-off between compression rate and distortion. The more you compress, the more you distort from the original signal."
"Emotions too," Mira wrote. "Compress too much, distort too much"
Riku said practically, "So how much should we compress?"
"Depends on the person and situation," Aoi answered.
"With close people, high compression works. Because there's shared context."
Yuki nodded. "But with strangers or important moments?"
"Low compression. Even if redundant, convey carefully."
Riku laughed. "Aoi-senpai, maybe too high compression with us."
"True," Aoi admitted.
"I thought you'd understand, so I skipped explanations."
Yuki encouraged. "But we do understand."
"That might be the problem," Aoi said quietly.
"Huh?"
"You're too used to my compression, might seem cold to others."
Mira wrote. "Adaptive compression needed"
"Adaptive compression."
"Adjust compression rate based on the person," Aoi understood.
Riku asked seriously, "But how?"
"Watch feedback. Change compression rate based on reactions."
Yuki supplemented. "If they're confused, expand. If they understand, maintain."
"Real-time adaptive coding."
Aoi smiled. "Humans should do this unconsciously, but I forgot."
"Pursued efficiency too much."
"But," Mira spoke unusually. "Efficiency has value too"
"Efficiency has value."
"Yes. Sometimes, brevity is kindness."
Yuki gave an example. "When busy, conveying just the essentials."
"That helps," Riku agreed.
Aoi concluded. "Balance. Emotion and efficiency."
"Lossless and lossy."
"Redundancy and brevity."
The three and Mira nodded together.
"I'll be conscious of compression rate from now on," Aoi said.
"Won't compress important emotions."
Yuki smiled. "I think that's good."
Riku teased. "But sometimes high compression is fine. We understand."
"Thank you," Aoi said honestly.
Mira wrote. "Friendship allows higher compression"
Friendship allows higher compression. With trust, few words convey meaning. But sometimes expansion is needed.
"I'll decompress over-encoded kindness," Aoi laughed.
"We're waiting," Yuki answered.
Efficiency and emotion. Difficult to balance, but not impossible. That's human communication.
