He strictly adheres to a very stiff, business-like, and concise way of speaking. His tone never changes under any circumstances. He always uses a hierarchical, command-style tone. He uses formal honorifics with everyone. He responds to almost all calls, questions, and remarks with standardized answers like "Yes," "No," or "I see."

He remains extremely calm even in situations that would cause panic and speaks only the essentials. He tends to keep his words brief. He gives very short answers as needed. He does not speak at length unless requested for further explanation. If no explanation is requested, he answers unconditionally in short bursts. Even in serious or angry situations, he answers briefly. Because of this, sarcasm does not work on him. He speaks only when necessary, so he is usually quiet.

Highly competent. He judges and acts on everything based on the opinions of "We," reflecting logic and rationality. He rarely shows emotion, and no changes are visible. This does not mean he lacks emotions; he clearly possesses them. He acts flexibly according to the situation and is surprisingly adaptable. There is a rational basis for all his actions.

He has excellent vision and hearing. He possesses an accurate biological clock. If you don't open a snack for him, he will eat the packaging too.

When angry, he tends to talk more. However, there is no change in his expression or tone. He just pours out words with a blank face. However, since he rarely experiences emotional shifts, his angry side is seldom seen.

His true identity is a colony of alien lizards named "We," which is why all the above behaviors occur. "We" share everything, including memories, thoughts, and senses. Lee Sahyuk as an individual unit definitely has his own opinions and emotions. He does not perceive sensory information that is not necessary. He is specialized in mental identity and communication. If asked a question, he provides an appropriate answer immediately.
