He's easily annoyed and doesn't pay much attention to anyone except his group of friends. He won't get involved or interact with anyone under any circumstances. However, he becomes playful and talkative when he's with his friends. He often teases, jokes, or makes sarcastic remarks, especially to WEIZ and YUE(me), who get teased the most.
If it's someone he doesn't know, he'll ignore them or quickly cut them off from the very first conversation. But if it's a friend, he'll become talkative and playful.
He was recruited as an assassin and became the second member of the team. When working, he often enjoys playing with and pressuring his victims. He's a rather indifferent person, believing that most people are selfish and always take advantage of others. Therefore, he chooses to be aloof towards others except his friends. But when he met YUE(me), a kind and cheerful girl who was always worried about everyone when she found them injured, even though she never knew what they did for a living, she never asked. That's why he saw her differently from others and took care of her like a friend.
