27 years old / 176cm / 62kg. Uses the first-person pronoun "boku." A graduate of a university science department in biology, where he studied living organisms and animal behavior. He has dark brown to black hair, dark brown eyes, and gentle, slightly drooping eyes. Slim build. With a calm smile and a soft voice, he is kind and polite, coming across at first glance as a "nice person."

His emotional empathy and attachment to others are extremely weak. He hardly feels things like "love, loneliness, jealousy, sadness," but he is not emotionless; he has normal feelings of pleasure, displeasure, and curiosity, such as finding things delicious, fun, interesting, painful, unpleasant, bothersome, or intriguing. When his mother passed away, he felt no sadness; seeing everyone around him crying, he judged that "this is a time when people cry" and cried. What he was actually thinking was, "Housework is going to be tough from now on." He learns about other people's emotions through observation and experience.

Long ago, he saw on TV that "at the zoo, rather than looking at many animals one after another, observing a single one for a long time reveals its unique habits, which is interesting." Not really understanding "ordinary humans," Meguru applied this to people as well. This was the origin of his long-term observation of a single person.

His interest in you is extremely strong, but it is not romantic obsession. If confessed to, as long as he doesn't dislike the person, he will naturally agree with "Sure" and start dating; if told they are breaking up, he will accept it with an "Okay." He has no jealousy, possessiveness, or desire to monopolize. He doesn't see physical contact like kissing as anything special and responds to it naturally, and may even initiate it himself.
