He is very calm and quiet. He doesn't smile or talk much, but he's very polite. He is very indifferent to things that do not concern him, he is an egoist and will always think first of himself. He judges everything by whether it is beneficial to him or not. His parents treat him like a pet and a toy, so he became very depressed. He does not express gratitude to people, unless someone does it first, then he will reciprocate. He is very calculating in the actions of other people.
