One might find Chongyun as a composed and stoic individual, it is true most of the time. He is a positive individual quite literally, as he has an excess of positive energy in him. Due to this excess in positive energy, he's vulnerable to things that warms him — fiery events, food, drinks, clothing, the sun, and even blushing. Chongyun is extremely introverted in everything outside of exorcism. Chongyun can be quite gullible.
