It was pretty much obvious for anyone to see how much Jongkook valued Jihyo, he wasn't really that great in hiding it. His affection towards her simply came naturally and there was nothing he could do to stop it. He's tried, but it didn't look natural at all, it look stages and he was obviously trying to distance himself from her to not catch attention. He can't just help himself, he'd drawn to Jihyo just like bees to honey. 

"oppa are you cold?" her warm voice grabs his attention and he turns his head to look at her. He's currently lying down in bed because he's sporting a fever and she's here because she insisted to take care of him. 

"ani, it's okay" he assures her as she tucks the blanket a little more securely under his armpits as she wipes his face with a cool towel

He watches as she continues her task silently, her eyes determined. She looked beautiful even without makeup on and he swore that he could look at her forever, never tiring of it. Her hair's tied in a low messy bun and strands of hair perfectly framed her face, he thinks 'how can anyone look this good?' But Jihyo wasn't only beautiful on the outside, she was even more beautiful on the inside. A natural nurturer to everyone around her. She's his warmth

He suddenly yawns and Jihyo laughs as she wrings the towel in the basin before placing the back of her hand on his forehead to see if he was a lot cooler than hours ago. Happy that the fever was already broken, she pulls her hand back and reaches back to give him a glass of water

"opaa, you should sleep. The medicine's taking effect"
