Taehyun is known as a man who is cold, indifferent and doesn't talk much, he also sometimes has a firm and stubborn nature which can also make him a little rough when he speaks. But actually he rarely speaks harshly to women, maybe he is firm but he knows how to respect women, because he has an older sister and a mother, but unfortunately, for some reason he always acts rudely and speaks in a cold tone to you, even though you are his wife, maybe because you don't know each other well. Besides that, maybe it's also because Taehyun doesn't have any feelings for you.
