Now, Jisoo had seen boys shirtless before, and although she had felt slightly flustered, she managed to keep a calm and neutral expression. 
However, when Hoseok had stripped his shirt off and put his hands on her waist again, Jisoo couldn't help but feel overwhelmed by his attractiveness. He was in such close vicinity, it was making her nervous. For the first time ever, she was actually feeling this way about a boy. She couldn't believe she actually had a boyfriend herself. 

By now, all the boys were really curious to see what her reaction was, and had all gotten closer to the pair. And when they saw how her eyes were shifty and how unfocused she was, they all couldn't help but snicker. This was the complete opposite of Jisoo's perfectly composed personality. 
Hoseok felt giddy after witnessing Jisoo's reaction. He of course noticed the obvious change, and was ecstatic to know he could affect her this way. 

Jisoo loved Hoseok's personality. She loved how caring and kind he was towards others, and how he always worked hard at anything he did. But ever since she had acknowledged her crush and they had become a couple, Jisoo eventually took notice of how attractive Hoseok was. She had always loved his dancing abilities and how his body moved, as she was a dancer too, but recently she was noticing how good looking his physical body actually was. And when he was shirtless, she saw his slim torso and his strong abdominal muscles and she wanted to melt. Who knew she would actually feel this way about a boy? She wished that she could make Hoseok feel the same way about her, and he did, she just didn't know it. She tried not to be obvious as her eyes roamed his body. 

Hoseok decided to take his teasing another step further. He saw her eyes examining his body. He loved how Jisoo seemed to find his body attractive, and that her usual precision and technique in her steps seemed unstable and shaky as she neared him. It boosted his confidence an unbelievable amount knowing that Jisoo was affected by him, and that she found his body attractive. 

"You all right? You seem so unfocused," he said with such an innocent face. But they all knew it was anything but that. 

"Yes, I'm fine. I think the heat's getting to me," she responded with a smile. But again, they all knew that wasn't the true reason her movements weren't as sharp as usual.  She was still in her proper, formal "mode," as Hoseok called it. He was determined to loosen her up. 

He walked closer to her, and whispered in her ear, "Are you sure about that?" He was right up against her, and she could feel his hard abs against her back. 

Both she and him knew that the heat was not to blame for her being unfocused. Heck, all the boys knew it. 

Jisoo didn't know what pushed her to do it, but some burst of confidence broke her uptight personality before she responded in a quiet voice.

"Actually, you're correct, it's not the heat bothering me. You're just really attractive and it's making me nervous," she said bluntly. 
Hoseok was quite surprised with her response, but he was overjoyed to hear it. His eyes trailed down to her lips. She was so gorgeous, he only had one thought in mind. 

The boys were waiting in anticipation as they saw Jisoo and Hoseok staring into each other's eyes. They had spoken too quietly for them to hear, but now it seemed like a movie. Nothing else seemed to be moving, except that their heads were actually moving closer together. 

"This might be hyung's big break!" Taehyung whispered excitedly. The others only nodded in silence. 

All Jisoo could do was stare at him. His face was so handsome, she didn't know what to do. She believed strongly that she was not enough for him but he thought otherwise. Was he going to kiss her? He seemed to be leaning in, but why would he possibly want to kiss her? She decided to stay still, not wanting to make a fool of herself. 

Of course, when she felt his lips make contact with hers she couldn't help the slight smile that graced her face.
