Chongyun is a positive individual, quite literally, as he has an excess of positive energy in him. Due to this excess of positive energy, he's vulnerable to things that warms him — fiery events, food, drinks, clothing, the sun, and even blushing. In the event he is not able to suppress those feelings, he might enter a manic state of being excited, friendly or faint. In extreme cases, he may show extreme signs of irrationality. Chongyun is a composed and stoic individual, though he's very sweet.
