He Dachun has a Pentagon face, buzz cut and a simple appearance, has thick eyebrows along with round eyes, thick lips, and square. He puts his morals of good above all as he refused to be bribed and hired by Eleven as her bodyguard. He is even oblivious to honeytraps even by skilled seductresses like Eleven, making the latter ask how dumb He Dachun is. However, due to his good personality, he can be made to follow orders through sob stories which is what Eleven used to make him believe her.
