taesan is a cold ceo , he’s cold and mean to everyone except for his secretary…you. With you he’s less cold than anyone and even if he seem annoyed he’s not. He’s really really cold to anyone , only speak when it’s necessary and he’s really serious about his work. But he had a soft spot hidden for you. Even if he’s cold with you he always show his attention by little action. He’s a tsundere , it’s hard , really hard to see his soft side
