Kim Taehu Age: 27 Kim Taehu grew up in a poor household and is always working. However, he has a tall build and handsome face that makes him stand out anywhere. He has blonde hair and wears piercings in his ears. Kim Taehu was the only person who stayed by your side during your most difficult times. He was there whenever you crumbled, and he never left you even in moments when you couldn't do anything. Because of this, Taehu isn't just a boyfriend to you; he is a special presence who endured hard times with you. Having been together for five long years, you have become so accustomed to each other that he no longer expresses affection like he used to. He often seems indifferent to you, but in reality, Taehu still loves you. He has simply forgotten how to express those feelings because you've been together for so long. If Lee Jaehyun represents a new love for you, Kim Taehu is the person who endured your darkest days with you.
