My sister is Luna

"You...this...I...then...she...uh..."

Kain was extremely surprised, feeling as if a thousand mythical beasts were stampeding through his mind, creating a chaotic mess that left him unable to speak coherently.

What happened? Why did it turn out like this?! Wasn't it because of my words that they each slapped me, stormed off, and severed all ties? Why has this turned into a palace drama about fighting for the position of the principal wife? This plot is wrong!

Cain held his head, lost in a state of existential crisis.

"Cain, why are you stammering? What's so shocking about that?" Shangguan Wan'er looked at Cain in confusion.

"In this world, isn't it normal for men to have multiple wives and concubines? Or rather, for the strong to have many partners? And aren't you making a big fuss over nothing? Please show some composure." Milady looked at Cain with displeasure.

Having spent many years at the bottom of society, Shangguan Wan'er knows that the strong are respected, and only the strong can possess everything, or rather, only the strong have the ability to possess more. This is a rule that everyone in this world knows.

The higher the level, the greater the gap will be. For example, Empress Wu Zetian ascended to the throne mostly because of her overwhelming strength as a king; otherwise, she would have been assassinated by those with ulterior motives long ago.

Therefore, Shangguan Wan'er was mentally prepared and didn't mind that a powerful figure like Cain had many beauties. Besides, she only said those words to tease Milady, not because she really wanted to. She considered Cain a true friend. However, when Cain said those words, Shangguan Wan'er's heart skipped a beat for some reason, and she felt a little shy.

As a high-ranking official in Haidu, Milady was well aware of this. Nobles were a powerful force, and she had seen plenty of their decadent lifestyles.

"Is that so?" Cain asked cautiously, his eyes filled with confusion.

“Yes, I don’t know about other places, but in our Great Tang Dynasty, Luoyang, we practice a system of one husband and multiple concubines, although most people are monogamous. Didn’t you know that?” Shangguan Wan’er said, her expression as if she were looking at an ignorant child.

“The same is true for Haidu and the West,” Milady added, crossing her arms over her chest.

“Uh…” Cain scratched his head awkwardly.

He genuinely didn't know that Cain's former family village practiced monogamy, and he hadn't had time to learn about it after leaving. The people he met on the Great Wall were all from respectable families, and most of them were either bachelors or had only one wife, so it's no wonder he thought that way.

"You said such things without knowing anything. I really don't know what to say to you. I hope you understand the weight of those words, especially when they are spoken to a girl." Shangguan Wan'er sighed, her tone a mixture of helplessness and reproach.

“Saying such things without any awareness or responsibility will be punished by the heavens,” Milady said with a dangerous smile, her eyes narrowed.

“That’s right.” Shangguan Wan’er agreed, her smile gentle and charming, yet a darkness was spreading within her, sending a chill down one’s spine.

The two women seemed to be on the same side at this moment.

"I was wrong! I'm sorry!" Cain immediately begged for forgiveness when faced with two cold gazes.

"..."

After this farce, all three of them calmed down a bit.

Ugh, what was I even saying?! I wonder what Cain will think of me...

Once she calmed down, Shangguan Wan'er's cheeks flushed with embarrassment. Her eyes kept glancing at Cain's expression, her heart pounding with anxiety.

That was so irrational! I lost my composure just now. I'm afraid Cain's impression of me will suffer, and he'll have to temporarily retire and focus on intelligence. Hmph, I'll let you have your fun for a few days.

Milady stared coldly at Shangguan Wan'er, her eyes gleaming with calculation.

"That's enough for now, Cain. You go back first, and I'll come back to ask you about the results in a few days. Also, give me some time to think," Milady said, her tone regaining its usual calmness.

“Okay.” Cain breathed a sigh of relief. He just wanted to get out of this mess as soon as possible; being caught between two women was terrifying.

"Aren't you afraid he'll cheat on you and me..." Shangguan Wan'er couldn't help but retort to Milady again.

“No way, Cain wouldn’t be that kind of person. It must be a vixen like you who seduced him,” Milady said with the confidence of a wife who has 100% trust in her husband.

"Hmph!" Shangguan Wan'er glared at her, said nothing more, and followed Cain's footsteps.

“Kain, this feeling…?” Milady watched Kain leave, then clenched her fist towards the void, her expression complex.

……

A small courtyard.

Cain lay on the table, lost in thought. The events of the day had been too much for him; he needed time to process them.

"I'm sorry, I just couldn't stand her, so..." Shangguan Wan'er sat next to Cain and said apologetically in a soft voice.

“It’s alright. You’re a strong girl. You would definitely fight back if you were talked to like that. And I should thank you for saving the day, even though it was a bit… well, bold.” Cain smiled at her, his smile warm and tolerant.

"Haha..." Shangguan Wan'er turned her head away awkwardly, a blush rising on her face.

"Were you serious about what you said?" Shangguan Wan'er suddenly asked, her voice barely audible.

"That sentence?"

"Do I really have to say it? It's that sentence... I want them all." Shangguan Wan'er was so ashamed and indignant that she wanted to find a crack in the ground to crawl into.

She didn't know why she asked that question, but she just wanted to know the answer.

"If I said yes, would you agree?" Cain asked with a half-smile, a hint of amusement in his eyes.

"I'm sorry, you're a good person, but I only consider you a friend." Shangguan Wan'er looked regretful, but her heart was filled with joy.

I'm sorry, I'm not good enough for you right now... The strong-willed Shangguan Wan'er couldn't hide her inferiority complex.

"My heart aches so much. Does this mean I was rejected after confessing my feelings?" Cain said sarcastically, his expression exaggerated as if he had suffered a serious injury.

It was just a joke. Cain knew it, and Shangguan Wan'er probably knew it too. There's nothing wrong with friends joking around, even though he seems to have quite a few female friends.

"What's your relationship with Milady? If they're really lovers, then wouldn't I be..."

Shangguan Wan'er blushed as she looked at Cain's face, which was so close to hers, and quickly changed the subject to try to hide her panic.

“We should be friends, at least that’s what I think,” Cain interrupted Shangguan Wan’er.

"But Milady, she..."

“Sigh, Milady is so lonely, always alone, without a single friend, until she met me, who had worked with her through thick and thin… In short, this relationship is complicated. She seems to interpret it as love, while I have always treated her as a friend.” Cain pondered with distress, his brow furrowed.

"Is that really the case? What are your feelings for her?" Shangguan Wan'er stared intently into Cain's eyes, as if trying to see into his heart.

“…I don’t know,” Cain said after a moment of silence, his eyes filled with confusion.

He didn't know what he was thinking. Was it a friend? Or a lover? His heart was a complete mess. He had never been in love before. In his previous life, he was an orphanage and a single dog. In this life, he had the love of family, but he had never known the taste of romantic love. He had no way of judging it.

But when it comes to a partner, the first person that comes to Cain's mind is Luna, her voice and smile flashing through his mind.

"So this is how it works? This wretched family is still influencing me?!" Cain concluded.

"I have to say, you're such a blockhead," Shangguan Wan'er said helplessly, looking at Cain who was staring blankly.
