Hongbin likes fixing Hakyeon's hair. He's not sure if it's because the strands of hair are so soft despite the abuse it was put it through. Or if it's because fixing Hakyeon's hair is a small thank you for everything that Hakyeon ever did for him. Or maybe it was that blindingly bright smile he got when he finished...no, no it was definitely the smile. That smile was his favorite thing about Hakyeon.
