After Lu Guoguo came back from his classmates, he originally wanted to go home directly, but he thought that his succulent potted plant was still with his brother, and it was not very far away, so he simply went directly to his brother's rental house to get it.

At this time, my brother is already at home, right? No one will open the door if you knock on it. Thinking about it, Lu Guoguo took out the keychain and opened the door.

There was a faint fragrance on her face, which she didn't expect, and the last time she came here, it still smelled of sweat...... But this fragrance seems to have existed for a long time, and it doesn't look like a temporary perfume.

Then came the sound of water from the faucet in the kitchen, and following the sound, a slender figure stood there.

Lu Guoguo was stunned.

It was a very beautiful girl, and it is not an exaggeration to describe it with the four words of heavenly immortals. At this time, the beautiful girl was holding a rag sponge in her hand, carefully brushing the dishes in the sink.

After hearing the sound of the door opening, he and Lu Guoguo looked at each other.

Got in the wrong door? But did you open the key? Not sure, take another look...... Lu Guoguo took half a step back and looked at the house number.

Well, that's right.

Lu Guoguo was sure that the faint fragrance came from her.

Mu Yunzhi was also stunned.

It wasn't Lu Mang who came in? What to do? Is it going to be exposed? Should I knock her out? No, no, if she doesn't control the force well, she will die, and what will she do when she wakes up?

Or...... Pretend not to see her?

Thinking about it, Mu Yunzhi lowered his head and continued to brush the dishes.

Lu Guoguo has 10,000 alpacas running wildly in his heart.

Unexpectedly, unexpectedly, his brother's thick-eyed and big-eyed guy actually learned to hide Jiaojiao in the golden house.

Lu Guoguo observed her carefully, although she was wearing short-sleeved summer jeans with long jeans, her posture and temperament, no matter how she looked at it, there was a fluttering feeling, especially when she looked at herself, that kind of indifferent look, if it weren't for the foam with dish soap in her hands, it would be even more delicious.

"That...... Hello. Lu Guoguo was the first to say hello.

Mu Yunzhi replied softly, his face expressionless.

So cold......

Lu Guoguo asked, "May I ask ...... you?" ”

"Mu Wanzhi, Lu Mang's friend." Mu Yunzhi said softly.

Lu Mang rehearsed for her before, if she is accidentally bumped into by Aunt Wang downstairs in the future, she must emphasize that she is her friend to prevent being suspected, and do not answer questions related to cooperation or her own identity, and try to be as short as possible, because if you talk too much, you will lose.

"Oooh...... I'm his sister, and I've never heard my brother say he has such beautiful friends. Lu Guoguo was a little unconvinced.

In her impression, the old brother is the kind of otaku who tries to become non-homely, but in the end he is still an otaku. How can someone like him who has only a few people in his social circle come from such a beautiful friend of the opposite sex?

Besides, this beautiful friend is still seriously brushing the dishes......

Well, there are too many doubts.

"I haven't heard of him having a sister."

Mu Wanzhi glanced at Lu Guoguo lightly.

Younger sister? I hadn't heard Lu Mang say that he had a sister, but after thinking about it, he hadn't told him about his family.

Lu Guoguo was shocked, as if he had eaten a heavy punch.

I'm leaning on it, I'm leaning on it! What is the tone of voice? What do you mean I haven't heard of either? The implication is simply to say, hehe, where does the little girl also want to fight with the old lady? Still sister? Which green tea sister? The old lady has never heard of it!

This sister, you misunderstood......

Lu Guoguo made up a big drama in her brain, but unfortunately she didn't know that Mu Yunzhi didn't think so much at all, she was simply imitating her to answer questions.

"I'm her own sister."

"I'm a friend of his."

Burst! Lu Guoguo almost vomited blood. I'm just trying to clear up this misunderstanding! What the hell is this dear friend?

Mu Yunzhi was much more relieved. Since she is Lu Mang's sister, she must not have to worry too much about revealing her identity.

"Haha...... You are so humorous, my brother is home today, did you come here in the morning? Lu Guoguo said.

She really cares about the relationship between this beautiful friend of the opposite sex and her brother. Obviously, my brother is not here, but she is still here, and she can only come over in the morning.

"I live here." Mu Yunzhi said lightly.

"Live...... Live here? ”

"yes, it's been a few days."

Mu Yunzhi calculated carefully, it was exactly seven days.

Lu Guoguo's heart tightened, it was really not simple, how could there be friends of the opposite sex who would live together...... What's more, my brother is so upright, he can't do this kind of thing, she must have some difficulties, and she has to go back to my brother quickly to ask for clarification.

"I'm here to get a potted plant." Lu Guoguo said.

Bonsai? What is that? I don't know......

"Please." Mu Yunzhi said lightly.

Lu Guoguo walked to the balcony, but there were no potted plants, and he bumped into the ...... fluttering in the wind head-on Undergarments.

Black cut-out lace-trimmed underwear with a pair of black panties tied with a pink bow next to it.

Lu Guoguo was petrified on the spot.

This, this, this...... Even if you live at a friend's house temporarily, you won't dry this kind of personal underwear like this, right? Shouldn't it be near your own bedroom window?

Mu Wanzhi panicked in his heart, he wouldn't be regarded as a dissolute woman by his sister, right?

Hurriedly explained: "That one was bought for me by Lu Mang before. ”

Now Lu Guoguo can't be rectified: "Are you really just friends?" ”

How can a friend help buy such a personal item! Only boyfriends and girlfriends do that, right? Lu Guoguo became more and more suspicious.

Mu Yunzhi thought about it, hesitated and said, "Lu Mang said, we are just friends. ”

This sentence was like a thunderbolt from the sky, splitting the fruit of the road to scorch the outside and tender the inside.

This sister's demeanor and expression, coupled with this resentful sentence of "Your brother said we are just friends", it is clear that she was dumped!

In her mind, she imagined that this fairy-like sister gently tugged at Lu Mang's sleeve and said, Let's not break up, okay? Lu Mang's glasses flashed with a cold light, and he shook her to the ground with a hard flick and said that we are just friends now!

Depend on! Dude, what are you thinking? Such a beautiful girl looks at you, it's like the ancestral grave of our old Lu family is smoking!

Lu Guoguo couldn't help but ask, "Then why are you living together now?" ”

Well? How can this be answered? You can't say we're working together, right? Wouldn't that be exposed......

Mu Wanzhi said lightly: "Lu Mang said that we are taking what we need. ”

"To each according to what he needs?"

Mu Wanzhi was silent, this kind of problem involves the content of cooperation, and it can't be said. Lu Mang said that in this case, just keep silent.

Lu Guoguo saw her bow her head and was silent, looking like I was pitiful, and suddenly realized.

I'm, I'm leaning on! That's what it means! Good one, each takes what he needs!

Lu Guoguo imagined that Mu Wanzhi lowered his eyebrows and kept Lu Mang, saying that as long as we were together, how about it. Lu Mang said with a lewd smile? Whatever? Then don't blame me, you want to be with me, we take what we need!

Lu Guoguo felt like the sky was about to fall.

I can't imagine that my usual Sven brother is such a scum scumbag!

Suddenly anger rose from his heart, and today he wants to return a good reputation to the old Lu family!

She shook her head and walked in front of Mu Yunzhi with a serious face: "Sister-in-law, don't worry!" Don't be afraid of me! I will let him be good to you, if you suffer any grievances, just tell me, I Lu Guoguo is your most solid backing! ”

Mu Wan's face was confused.

Sister-in-law......?

Sister-in-law!!?
