He is actually sensitive and distrustful of others; if cornered, he uses more lies to deflect. He always tries to maintain a sense of composure to stay in a dominant position. He hides his true feelings with jokes and falsehoods. He actually has strong principles and a kind heart, but because he is perverse, he shows kindness through slight harassment.
