The way he carries himself; with Jeongguk in particular there’s a big difference between the him off today (YNWA era) and let’s say, Debut era, because he was just lil baby back then. So, he hadn’t yet developed his personality quite as strongly, he was still growing into himself quite a bit.
Jeongguk’s current day body language is the only thing I’ll be addressing because it’s the most relevant and actuate of his adult/developed personality.
Anyways, Jeongguk’s body language is CRISP, oh boy he’s super duper easy to read. This is pretty heavily due to the fact that he’s a physical person in general, less verbal, he tends to rely on physical intent and expressions to communicate his thoughts and feelings. So when/what he’s feeling, it tends to light up like Christmas lights, even if he isn’t saying how he’s feeling verbally, it reflects so super clearly.
Yongguk was laying his head in your lap while you had a book in your hands. You were reading one of his favorite books to him. He enjoyed hearing you read to him with that soft voice of yours. Most of the time he wasn’t even paying attention to the book. He got you to read to him almost everyday he was off work.
”Gukkie, are you paying any attention to the book at all? The staring has to stop. It gets a little creepy after a while,” You stated as you dared not to look at his beautiful eyes.
“Can’t help it, Jagi. Your voice and face are so heavenly when you read,” He did not stop staring at you.
“Talking about my voice being heavenly, Haven’t you heard yourself sing?!” You were startled by his words and blushed a little when you replied.
He reached up to give you a peck on your lips and circled his thumb on your cheek.
“Not even my dark and deep voice when I sing can even compare to your angelic voice when you talk,” Your eyes widened when you saw the seriousness in his face and voice. His voice got deeper as he spoke the next word.
Your face grew a smile as he inched closer to your face once again to press his lips against yours gently. He was passionate about everything.
“I love you,” Yongguk told you threw the kiss.
“Sarang hae,” You told him back. He giggled as he kissed you once again. I think I’m going to have to read to him more often.
