Strange noises came from the second floor.
While Shirou was going back to his room from the kitchen, he heard strange sounds from upstairs. Out of confusion and curiosity, Shirou went towards the direction of the sounds.
When he got to the second floor, a sound that made him uneasy started.
The sound came from Paul and Zenith's room.
Because the original big house had burned down, the Greyrat family's temporary house now was much smaller than the big house before.
After thinking about it, Paul and Zenith moved their bedroom to the south side of the second floor, let Lilia live on the north side of the second floor, and Shirou and Rudeus's rooms were arranged on the first floor.
Roxy now lived with the Greyrat family, and her room was next door to Lilia's.
This temporary house was much smaller than the old big house, and the soundproofing was also very bad. Even small noises in the room could be heard in the hallway.
Because of this, the sounds of Paul and Zenith making babies couldn't be hidden even if they wanted to.
As soon as Shirou walked up to the second floor, he heard the sound of the two of them shaking the bed, making creaking and moaning noises.
These two really have a lot of energy. It looks like Rudy and I will have a younger brother or sister soon.
Shirou thought calmly in his mind.
Yes, because Paul and Zenith basically did baby-making exercises with such energy every night, Shirou was almost used to this kind of sound. He treated this sound, which made normal people uneasy, as ordinary background noise or background music.
In fact, before Rudeus was born, he was already used to this couple's overly active sex life. He was so tired of these sounds that he couldn't be more tired of them. He now completely converted these sounds in his mind into sounds similar to birds singing and frogs croaking outside.
Because of this, Shirou was sure that the strange sound he had just heard was not the sound made by Paul and Zenith when they were making babies.
That sound was more like something rubbing against the floor.
"Could it be that I heard wrong?"
Walking up to the second floor, Shirou glanced around and found nothing unusual.
He suspected that it was just his imagination and was about to walk down the stairs and return to his room, but suddenly he noticed a strand of blue hair flashing in the shadows.
Based on some instinct, Shirou hid almost immediately. He didn't even know why he wanted to hide, but his intuition still made him take this action.
He secretly observed the hallway ahead and found that Roxy had secretly come to the door of Paul and Zenith's room at some point. Her eyes were wandering around and she was standing there sneakily.
Roxy? Why is she here?
Shirou remembered that Roxy's room, like Lilia's, was on the north side of the second floor, some distance away from Paul and Zenith's room.
There was no reason for her to be here. Even if she wanted to go to the bathroom, she shouldn't stop at the door of that couple's room.
What purpose did Roxy have for wanting to peek into Paul and Zenith's bedroom?
Shirou couldn't understand Roxy's actions at all. He almost instinctively observed her actions. It wasn't that he suspected Roxy had any bad intentions, but he was just curious and alert.
If Roxy didn't do anything, he would just apologize for his peeping later.
That's what Shirou thought. But something seemed wrong?
After arriving at the door of Paul and Zenith's room, Roxy didn't do anything special, nor did she use magic. Instead, she first looked around to make sure no one was around.
"Haa~ haa~"
Then, her breathing suddenly became rapid.
The girl's face was flushed, she was suppressing her somewhat rapid breathing, and her eyes were peeking through the crack in the door at the inside of the bedroom where the action was intense.
???
Under Shirou's surprised, even shocked, gaze, Roxy's body slid down to the ground little by little.
She stared at Paul and Zenith's room while making suggestive movements.
"Haa~ haa~"
Looking at Roxy's actions, Shirou's brain crashed.
All the original guesses and suspicions turned to ashes after seeing the shocking scene in front of him, leaving only confusion and chaos.
What... what what? What is Miss Roxy doing? She, she is actually...
Seeing Roxy's appearance, Shirou simply couldn't connect her with her usual serious and mature appearance. His brain was even blank, and his eyes began to get red.
Although Shirou kept hoping that everything in front of him was just his illusion, that everything he saw was just his eyes deceiving him, no matter how much he blinked or even pinched his arm, he couldn't make the scene in front of him disappear.
Roxy's increasingly intense reaction even made him unable to calm down, and his body gradually began to heat up.
Most importantly, Shirou had no idea what kind of reaction he should have now.
If he walked out now, Roxy would definitely find out, which would probably have extremely bad consequences, and might even lead to a life-threatening event.
But if he didn't go out now, wouldn't he become a pervert peeking at a girl?
Shirou's morals made him reluctant to do such an unbearable thing, but he couldn't just walk out, which would only make things worse.
As he hesitated, Roxy in the distance had already begun to enter an explosive state.
Seeing that she seemed to have gradually stabilized, Shirou's mind gradually became calm. He let out a long sigh and made up his mind to keep what happened tonight in his heart forever.
If Roxy knew that he had seen everything, I'm afraid either she would die, or I would die.
Shirou's expression became stiff. He prayed that Roxy could go back to her room immediately, and then he could also go back to his room, only to treat everything tonight as a beautiful dream.
However, whether it was a coincidence or inevitable.
After finishing, Roxy seemed to want to go to the bathroom and walked right towards Shirou, and at the moment of turning the corner, she bumped into him.
It's over! It's over!
At the moment when his eyes met Roxy's, Shirou only had this one thought in his mind.
A strong sense of despair made him completely unable to react. He could only awkwardly say, "Uh, good evening, Miss Roxy. Are you still practicing water magic so late?"
"..."
Hearing Shirou's words, Roxy seemed to be petrified and was stunned.
The two of them looked at each other, and even the air around them seemed to freeze.
