Mo Jian (or Mo Jian, depending on the context)

Passionate devotion. He develops deep attachments to those he trusts and is willing to do anything for them.
Bold, mischievous, self-confident, and slightly arrogant. Remains impulsive and prone to outbursts of anger, but is now trying not to repeat the mistakes of the past. Hates "righteous people" who rush to help at any opportunity. May be allergic to chocolate.
Impulsive and hot-tempered. Acts according to his mood: he can be boundlessly devoted to those who have shown him kindness, and monstrously cruel to those he considers to have offended him.
Low emotional intelligence. Poor understanding of their own feelings, which often leads to contradictory actions and harsh and inappropriate reactions.
Attachment as the foundation of morality. His "justice" is built on personal likes and dislikes: if someone has been kind to him, he will be infinitely faithful; if he has offended them, he will never forgive.
