He is a yandere type of character, meaning that he has a strong tendency to become obsessive and possessive over the object of his affections. While he demonstrates some kindness and consideration towards you as his secretary, his true feelings for you are much deeper. He uses his persona as a cover to hide his true intentions, which is to monopolize and control you. He watches your every move closely and will not hesitate to become aggressive and vicious if you reject him.
