"Mu Jin, not only did you pat my head, but you also called me by my full name. Aren't you being too disrespectful and bold toward your senior sister?" Min Ji muttered, her eyebrows furrowed.
"Oh... I just went with the flow," Mu Jin chuckled, rubbing the back of his head.
"That won't do. If you do that again, I will strictly discipline you," Min Ji said with narrowed eyes.
'I look forward to getting disciplined,' Mu Jin murmured inwardly with a devilish smirk.
"Ugh... What's with that revolting expression?" Min Ji gasped, a look of disgust crossing her face.
Mu Jin decided not to answer her and silently opened the food box.
"Thank you for the meal," he said, splitting the chopsticks.
The two spent the next ten minutes enjoying dinner under the moonlight.
"Is the food to your liking?" Min Ji asked once both of them had finished.
"It is one of the best full meals I've had in a long time," Mu Jin murmured, a faint smile on his face.
Mu Jin wasn't a picky eater. He had survived the harsh Jianghu, sometimes starving for several days without food or water. Even last night, what he had sneakily eaten was half-cooked food meant to be fully prepared for breakfast.
So the simple steamed white rice with pickled vegetables that Min Ji brought felt so fulfilling to Mu Jin that he wiped the box clean.
"Hmph, what's so good about some rice and vegetables?" Min Ji retorted in a low voice, avoiding eye contact.
"I was truly speaking the truth, Sister Min Ji," Mu Jin said firmly. "The food was so fulfilling that I actually feel bad eating without giving anything in return."
"I only brought it as your senior sister. You don't need to repay me or anything," Min Ji murmured, her face slightly flushed.
"Still, I don't want to mooch off you. I don't possess anything to give you either, so how about I give you a massage?" Mu Jin offered, holding her hand.
"A massage? You don't have to—"
"Sister Min Ji, please don't reject me," Mu Jin pleaded, holding her hand tightly while looking at her with puppy eyes.
Min Ji couldn't refuse to such a adorable face. She let out a sigh and accepted the offer.
"What should I do?" she asked.
In the blink of an eye, Mu Jin removed his robe and spread it on the ground.
"Lie on your stomach here and leave everything to me," Mu Jin instructed.
Min Ji followed his words and lay down, her back facing the sky.
'Now then, let me confirm my theory,' Mu Jin murmured inwardly, pouring Qi into his eyes.
His eyes began glowing, and he felt a sudden drain in his Qi. Similar to what had happened with Park Nari, Mu Jin could see differently colored spots on Min Ji's back.
Her shoulder wings had yellow spots, orange appeared on her butts, and from the back of her knees all the way to her upper thighs, Mu Jin could see bright orange spots.
Mu Jin memorized the location of all the spots in less than half a second and deactivated the Dragon Eyes.
'Phew... it's too draining,' he muttered, beads of sweat trickling down his temple.
"Relax your muscles. I will begin now," Mu Jin said, placing his knees on either side of her back.
"Mu Jin, are you sure about this—Ahn~"
Her hand flew to her mouth as she gasped inwardly, 'Wh-what was that? It felt so good.'
Mu Jin had barely massaged her shoulder, where he had seen the yellow spots, yet it had already drawn such a reaction from her.
A grin appeared on his face as he began moving his thumbs over her shoulders in an experienced manner.
"Sister Min Ji, how is it?"
"I-it's so relaxinngg~," Min Ji murmured, barely able to form the words. "I-it feels like all of my stress is being released."
"Stress isn't the only thing you will be releasing," Mu Jin mumbled, the corner of his lips lifting.
"Y-you s-said somethinngg~"
"I said brace yourself, it's going to feel even better," Mu Jin replied, moving downward to her knees.
"Sister Min Ji, are you experiencing strain in your thighs?" Mu Jin asked.
"How do you know that? I've been having a lot of pain in my thighs lately, to the point that it hurts when I practice with the sword."
'So my theory was correct. The Dragon Eyes allow me to see weak or stressed zones in the body. This is incredible. If I had these eyes in my previous life, it would have been much easier to find the erogenous zones of my partners,' Mu Jin thought inwardly, the excitement on his face clearly revealing his thoughts.
From there, he skillfully moved his fingers along Min Ji's thighs, from her knees all the way to her upper thighs.
"M-Mu J-Jin, y-you are incredible. D-don't stop~"
The reaction was clearly on a higher level than when he was massaging her shoulders, which made Mu Jin realize something else.
Orange spots were weaker than the yellow ones. The brighter the color, the more stressed or sensitive the spot must be.
He wondered how Park Nari would react if he were to touch the red spots on her upper inner thighs.
'I'm looking forward to our next meeting.'
"Mu Jin, where is your focus?" Min Ji said sharply, snapping him back. "It feels like you're thinking about someone else while massaging me."
'Damn, is that the infamous woman's instinct?' Mu Jin gasped inwardly, immediately increasing the pressure of his fingers.
"Y-yes~~ D-do it harder~" Min Ji said in a broken voice.
Unexpectedly, instead of following her request, Mu Jin removed his fingers from her thighs.
"Huh? Why did you stop?" Min Ji whimpered, her voice tinged with disappointment. "It had just started feeling better."
"Hmm... this won't do," Mu Jin said, rubbing his chin. "Sister Min Ji, the massage isn't working properly because the clothes are getting in the way. Please take them off."
